Classic wallets remain a staple in global fashion and accessories markets. Their enduring appeal lies in clean lines, functional layouts, and premium materials that age beautifully. However, behind every well-crafted wallet lies a complex assembly of specialized components — metal frames, leather panels, RFID liners, plastic inserts, and finishing consumables. Sourcing these parts from a single, reliable manufacturer ensures consistency, durability, and on-brand quality.
As a China-based OEM manufacturer with over 13 years of hands-on experience, we at GSTAR have produced thousands of wallet component sets for brands, wholesalers, and retailers worldwide. This complete OEM catalog guide covers every part category that goes into a classic wallet, helping you understand material options, customization possibilities, and how to specify each component for your next production run.
Whether you are developing a new product line or upgrading an existing design, this guide will walk you through frames, leathers, RFID shielding, molded parts, and packaging — all from the perspective of a manufacturer that engineers everything in-house.
The metal frame defines a wallet's structure and tactile feel. Common frame types include button snap frames, magnetic closure frames, and fold-over frames designed for money clips. Each requires precise engineering to ensure smooth operation and long-term durability.
We work with brass, stainless steel, zinc alloy, and aluminum — each material offering distinct hardness, weight, and finish characteristics. For example, brass provides a warm, traditional feel ideal for vintage-inspired designs, while stainless steel offers superior corrosion resistance for modern, minimalist wallets. Our engineering team collaborates with clients during the design-for-manufacturing phase to optimize frame geometry, spring tension, and assembly tolerances. With in-house CNC machining capabilities, we can produce complex frame shapes and surface finishes — brushed, polished, matte, or antique — and integrate custom logo engraving directly into the metal surface.
Card clips and money clips are essential for wallets targeting minimalist users. These components must maintain spring tension over thousands of cycles. We use spring steel for tension retention and stainless steel for corrosion resistance, depending on your design requirements.
Our in-house tooling department enables rapid prototyping of clip profiles. Clients receive functional samples before full production, allowing them to test insertion and removal forces, clip grip, and overall ergonomics. We also offer custom clip profiles — from standard straight-edge designs to curved, contoured shapes that match specific wallet layouts.
Small hardware — rivet caps, screw posts, hinge pins — can make or break a wallet's mechanical reliability. We manufacture these components with tight tolerances using our CNC turning and stamping equipment. Finishing options include electroplating (gold, silver, nickel, gunmetal), PVD coating, powder coating, and eco-friendly oxidation treatments.
Quality is non-negotiable: we test all hardware for salt spray corrosion resistance (up to 48 hours for plated parts) and torque consistency using calibrated tools. This ensures that every rivet and screw performs reliably in the field, reducing returns and customer complaints.
Leather is the soul of a classic wallet. We supply full-grain, top-grain, genuine leather, and bonded leather options for budget-conscious lines. Our sourcing partnerships extend to tanneries that meet REACH and OEKO-TEX standards, ensuring compliance for global markets.
Custom specification is critical: thickness ranges from 1.0 mm to 2.5 mm, with options for different tempers (soft, firm, or rigid) and textures (smooth, pebbled, or distressed). Our QC team inspects every leather batch for surface defects — scars, blemishes, grain irregularities — and evaluates dye lot consistency using spectrophotometers. This attention to detail ensures that every wallet cover matches your approved color standard.
Stitching defines both aesthetics and structural integrity. We offer saddle stitch (traditional hand-sewn look), machine lock stitch (for speed and consistency), and decorative contrast stitching for bold branding. Thread options include polyester, nylon, bonded nylon, and waxed linen — each with distinct strength, sheen, and flexibility characteristics.
Edge finishing is equally important. We provide burnished edges (a classic, hand-worked look), layered edge paint (durable and glossy), or raw cut edges (for industrial minimalism). Our library includes over 300 thread colors and 50+ edge paint shades, enabling rapid sampling without custom dye lots. For repeat orders, we maintain color master cards to ensure batch-to-batch consistency.
Sustainability is increasingly important for our clients. We offer microfiber leather, PU leather, recycled PET fabric, and vegan leather alternatives. These materials provide excellent abrasion resistance, colorfastness, and flexibility at low temperatures — ideal for wallets destined for colder climates.
Our team advises on material substitution when clients request lower cost or sustainable alternatives without sacrificing hand feel. For example, we have successfully replaced full-grain leather with high-quality microfiber for a 40% cost reduction while maintaining a similar tactile experience.
RFID protection is a growing expectation in modern wallets. We use non-woven copper/nickel fabric, aluminum foil laminates, and conductive polymer films to achieve attenuation levels of 40 dB to 80 dB, depending on material and layering configuration. All testing is performed at 13.56 MHz (contactless payment cards) and 860–960 MHz (passport and access card frequencies).
We integrate RFID liners seamlessly between leather and lining layers without adding excess bulk or stiffness. This is achieved through precise cut-and-sew patterns that match the wallet's internal geometry. For designs where weight is a concern, we recommend ultra-thin films that add less than 0.3 mm to total wallet thickness.
For slim-profile wallets where separate liners are not feasible, we use conductive threads stitched into the lining pattern. This technique creates an antenna-style blocking configuration that maintains flexibility while providing continuous shielding around card slots.
Our R&D team tests every RFID wallet design in our in-house RF shielded room before approving production. We use a calibrated reader and ISO test cards to measure attenuation across the full frequency range. This rigorous testing ensures that every wallet meets performance claims, regardless of size or material combination.
We follow ISO 10373-1 and ISO 14443 test methods for contactless card blocking verification. Clients receive a test report with each production lot, showing attenuation values at multiple frequencies. For regions requiring specific compliance documentation (e.g., CE marking, FCC compliance), we can provide supporting test data and coordinate with accredited labs.
Our QC team performs 100% testing for RFID attenuation on every blocking layer during production. This means that not a single wallet leaves our facility without verified shielding performance.
Transparent windows for ID cards and slide-in card holders are common in classic wallet designs. We use PVC, PETG, and polypropylene materials, each selected for clarity, flexibility, and durability. Food-grade PETG is ideal for ID windows that require UV resistance and impact strength.
Our injection molding workshop runs 8 presses with clamping forces from 50 to 200 tons, enabling us to produce everything from thin windows (0.3 mm) to thick protective frames (3.0 mm). Custom mold design is handled by our in-house team of 5 engineers with over 8 years of experience in small-precision molds.
Originally developed for graded card holders, our bumper guard molds have been adapted for wallet edge protection. These components prevent wear and tear on wallet corners and edges, extending product lifespan. Materials include TPU (for flexibility), silicone (for grip), and hard PC with overmolded rubber (for impact resistance).
We offer custom durometer options ranging from Shore A 60 (soft grip) to Shore D 80 (rigid guard). With over 200 bumper guard mold iterations already produced, we can often modify an existing mold for new wallet designs at reduced tooling cost. This accelerates your time to market while maintaining quality.
For specialized components — such as rigid card dividers, multi-layer frames, or hybrid metal-plastic parts — our injection molding team provides full design-to-production support. Typical turnaround is 15–20 days for a single-cavity prototype mold and 30–35 days for multi-cavity production molds.
We also offer insert molding, where metal hardware is embedded into plastic parts during the molding cycle. This reduces assembly steps for our clients, lowering overall production costs while ensuring dimensional accuracy.
Bonding metal to leather requires industrial-grade adhesives that withstand temperature changes, humidity, and repeated flexing. We stock neoprene contact cement, polyurethane reactive hot melt, and epoxy for metal-to-metal bonding. Application methods include spray, brush, roller, and automated adhesive dispensing on our assembly lines.
Before every production run, we test bond strength according to ASTM D903 (peel strength) for the specific adhesive and material combination. This ensures consistent adhesion across all units. For high-volume orders, we recommend automated dispensing to reduce waste and improve bonding uniformity.
Our toolroom designs assembly jigs that ensure consistent alignment of metal frames, card slots, and RFID liners. These jigs reduce assembly time by 30–40% on complex multi-layer wallets, which translates to lower unit cost for clients. Tooling is owned by the client or co-owned under a non-disclosure agreement, giving you full control over your production process.
We also provide assembly line training documentation and video guides for your in-house team, ensuring smooth onboarding during initial production runs.
Packaging is often the first physical touchpoint between your brand and the customer. We offer standard options like cardboard dividers, foam trays, poly bags, and branded hang tags. For premium lines, we provide rigid gift boxes with magnetic closure, sleeve boxes, and clamshell cases with logo embossing.
A key advantage of working with us is consolidated shipping: we source and coordinate all packaging components, so clients receive one shipment containing wallet parts and finished packaging, not separate deliveries from multiple vendors. This simplifies logistics and reduces total landed cost.
Every project begins with a detailed BOM that lists every part, material grade, color code, and quantity per wallet. We provide the BOM in Excel and PDF format, with reference photos and dimension drawings for each component. All BOM changes are tracked through a dedicated project manager, and revision history is maintained for audit purposes.
This documentation serves as your single source of truth for production, ensuring that every team — from sourcing to assembly — works from the same specifications.
Before mass production, we create a physical sample kit containing each part — metal, leather, liner, plastic, packaging — with labeled part numbers. Clients use this kit for internal approval, marketing photography, and assembly line training. Part numbers are cross-referenced in our ERP system, enabling accurate repeat orders with zero specification drift.
For clients managing multiple wallet SKUs, we offer a consistent numbering schema that simplifies inventory management and reorder processes.
Standard lead time is 25–35 days from BOM approval and deposit. Our standard MOQ is 500–1,000 sets per part number, with lower MOQ options available for add-on items like rivets or threads. For first-time clients or market testing, we can accept as low as 200 sets per design.
Bulk packaging options include kit-set (each set bagged together), loose bulk (individual parts bulk-packed), or sub-assembled modules (e.g., metal frame pre-attached to leather). We advise based on your assembly capability and target cost. Our logistics team has shipped to over 40 countries, providing air and sea freight arrangement support with real-time tracking.
Our QC lab is equipped with a tensile tester, Taber abrasion tester, drop tester, salt spray chamber, and RFID analyzer. Sampling follows AQL 2.5 (normal) for visual defects and AQL 1.0 for functional defects. RFID wallets undergo a 50-cycle card insertion/removal test before shipment, simulating real-world usage.
For metal hardware, we perform torque testing on screws and rivets to ensure consistent assembly forces. Leather components are tested for colorfastness (wet and dry rub) and seam strength. Every test result is recorded and available for client review.
Precision is critical for parts that must fit together perfectly. Metal parts are held to ±0.10 mm for formed components and ±0.05 mm for CNC-machined faces. Plastic parts maintain ±0.15 mm for general dimensions and ±0.05 mm for critical fit surfaces like hinge pins and snap buttons.
We provide First Article Inspection (FAI) reports with CMM (Coordinate Measuring Machine) data for new molds. For ongoing production, we conduct dimensional checks at defined intervals to ensure consistent quality across all batches.
Our production facility is ISO 9001:2015 certified for quality management. We support clients requiring REACH, RoHS, and California Proposition 65 compliance documentation. For export to specific regions, we can arrange SGS or TÜV on-site inspection with 48-hour notice.
Do you provide samples before production? Yes. Functional samples (assembled prototype) and component samples (individual parts) are available before mass production. Sample lead time is 3–5 business days for stock materials and 7–12 business days for custom finishes. Sample costs are deducted from the first production order.
Since our founding, we have completed over 800 OEM wallet parts projects for brands in North America, Europe, Southeast Asia, and the Middle East. Our engineering team has solved challenges including ultra-thin RFID integration, high-torque hinge design for money clips, and multi-material bonding for hybrid wallets. This depth of experience means we can anticipate and resolve manufacturing issues before they impact your timeline.
Our combined production lines — CNC machining, injection molding, leather cutting, and assembly — can produce over 300,000 set parts per month. We maintain a 30-day raw material buffer for high-consumption items like brass sheets and RFID fabric, preventing bottlenecks during peak seasons. This capacity ensures that even large-volume orders are delivered on schedule.
What is the minimum order quantity for classic wallet parts at GSTAR? Our standard MOQ is 500–1,000 sets per part number. For first-time clients or market testing orders, we can accept as low as 200 sets per design. Sample turnaround is 3–5 business days for stock material samples and 7–12 business days for custom color/finish samples. New clients receive a dedicated project manager and a Get a Quote within 24 hours of BOM submission.
What payment terms do you offer for OEM projects? Standard terms are 50% deposit with signed BOM and purchase order, 50% balance before shipment. For established clients and orders above $50,000, we can consider 30% deposit / 70% before shipment or L/C at sight. Payment methods include T/T, L/C, and Western Union.

Whether you are launching a new classic wallet line or upgrading an existing design with better hardware or RFID protection, having a reliable parts partner is critical to your product's success. At GSTAR, we combine 13+ years of OEM experience, in-house CNC machining and injection molding, and rigorous quality testing to deliver wallet components that meet your exact specifications — from metal frames and leather covers to RFID liners and packaging.
Stop sourcing parts from multiple suppliers. Let us consolidate your entire bill of materials into a single, coordinated production run with consistent quality and faster turnaround.
How long does it take to produce custom tooling for plastic parts? Prototype mold (single cavity) takes 15–20 days. Production mold (multi-cavity) takes 30–35 days. We provide mold flow analysis report before steel cutting and deliver T0 samples for client approval before production mold release.
Do you ship wallet parts as fully assembled wallets or as component kits? We offer both options. Most clients order component kits (each part bagged separately) to assemble in their own facilities. Some prefer sub-assembled modules (e.g., metal frame pre-attached to leather). Fully assembled wallets are also available for private label projects. We advise based on your assembly capability and target cost.
