If you are a wholesaler, brand owner, or online shop seller looking to source graded card protection, you know that a simple sleeve won’t cut it. A graded guard is a rigid, UV-resistant, and stackable holder designed specifically for graded trading card slabs from PSA, BGS, CGC, and SGC. It protects the investment-grade card from scratches, impacts, and light damage while allowing for clear display and easy stacking.
At GSTAR, we have been manufacturing graded card holders for over 13 years. Our factory operates with in-house CNC machining and a monthly production capacity of 300,000+ units. We provide OEM and ODM services to popular brands, wholesalers, and top online sellers worldwide. This guide is designed to help B2B buyers like you make informed decisions when sourcing graded guards—whether for a small trial order or a large bulk supply contract. We will walk through materials, manufacturing processes, customization options, and quality benchmarks, all from the perspective of a professional manufacturer.
A graded guard is a protective case engineered to fit the exact dimensions of a graded card slab. Unlike standard card sleeves, it offers rigid protection that prevents bending, scratching, and dust accumulation. Most graded guards feature UV-blocking properties to prevent fading during long-term display. They are designed to be stackable, allowing collectors and retailers to store multiple slabs safely without scratching each other.
Our graded guards are manufactured to precise tolerances to fit the most common grading companies: PSA, BGS, CGC, and SGC. Each slab brand has slightly different thicknesses and corner radii. Through our custom size and design services, we can adjust the internal cavity to match any non-standard slab format. This is critical for brands that work with niche grading services or want a proprietary fit.
Generic card sleeves are not suitable for graded slabs. They lack dimensional accuracy, clarity, and stackability. A professional graded guard must provide a snug fit, optical-grade clarity, and the ability to withstand repeated handling. For retailers, the packaging of graded guards also matters—it affects shelf appeal and customer trust. At GSTAR, our engineering support team works with you to develop custom dimensions, locking mechanisms, and surface finishes that meet your target market’s needs.
The choice of material directly impacts product cost, durability, and market positioning. Here are the three primary materials we use in our factory:
Rigid Polypropylene (PP): Lightweight, cost-effective, and offers high clarity. Ideal for budget-friendly product lines where basic protection is sufficient.
Acrylic: Provides a premium feel with superior scratch resistance. Commonly used for display-grade products aimed at high-end collectors.
PET (Polyethylene Terephthalate): Offers excellent UV protection and long-term archival durability. Suitable for products intended for long-term storage or retail display under lighting.
Your material choice will influence wholesale pricing, retail margins, and branding options. For example, acrylic graded guards command a higher retail price but require more precise manufacturing to avoid surface defects. PP is easier to produce in high volumes but may not appeal to premium buyers. PET sits between them, offering a balance of cost and performance.
At GSTAR, we perform in-house material testing to ensure consistent thickness, clarity, and impact resistance across every production batch. Our technical team helps you select the optimal material based on your target market—whether you are positioning a budget-friendly line or a luxury collector’s item.
Our manufacturing process is designed for precision and repeatability. Here is how we produce a graded guard from start to finish:
Mold Design and Tooling: Our engineers create custom molds based on your slab dimensions. We use computer-aided design (CAD) to ensure the internal cavity matches the slab profile within ±0.1mm tolerance.
Injection Molding or Thermoforming: Depending on the material and design complexity, we use injection molding for high-volume runs or thermoforming for prototypes and low-volume orders. Both methods are controlled for temperature, pressure, and cycle time to prevent warping.
Post-Processing: After molding, parts undergo deburring to remove sharp edges, polishing to achieve optical clarity, and optional UV coating application. Each piece is inspected for surface defects before packaging.
We implement multiple quality checks throughout production:
Dimensional verification using CNC-measured fixtures to confirm slab fitment.
Visual clarity inspection under controlled lighting to detect cloudiness, bubbles, or scratches.
Drop test and stress testing to ensure the guard can withstand impacts during shipping and handling.
Our factory’s 300,000+ monthly production capacity allows us to fulfill large B2B orders without compromising quality. In-house CNC machining enables rapid prototyping and mold modifications—eliminating third-party delays. We also offer flexible MOQ, accommodating both trial orders and bulk contracts. This infrastructure ensures that whether you need 500 or 50,000 units, the quality remains consistent.
We offer a wide range of customization options to help you differentiate your product line:
Dimensions: Adjust internal cavity size for non-standard slabs or unique locking mechanisms.
Color and Transparency: Choose from clear, frosted, tinted, or opaque finishes.
Surface Finish: Select matte, gloss, textured, or anti-glare coatings.
Branding: Add logo embossing, pad printing, hot stamping, or adhesive labels.
OEM (Original Equipment Manufacturing): You provide the specifications, and we manufacture to your exact requirements. This is ideal for brands with established designs.
ODM (Original Design Manufacturing): Our R&D team proposes designs based on market trends and your feedback. You can then select and modify the design for your brand.
Private Label Packaging: We support custom packaging including blister packs, display boxes, and hang tags for retail distribution.
With 13+ years of experience, we understand the nuances of card protection products. Each OEM/ODM account is assigned a dedicated project manager to ensure clear communication and timely delivery. Sample turnaround is typically 5–7 business days. Contact Our Team to discuss your custom graded guard requirements.
When sourcing graded guards, verify these metrics with your supplier:
Dimensional Tolerance: Acceptable variance for slab fitment should be within ±0.2mm. At GSTAR, we maintain ±0.1mm for most products.
Optical Clarity: Light transmission should exceed 90% for clear materials. Haze measurement should be below 2%.
Chemical Resistance: The material should not off-gas or degrade over time, which can damage the card.
We ensure our products meet international standards:
Material Safety: RoHS and REACH compliance for EU markets.
UV Resistance: Testing per ASTM D4329 to confirm long-term display suitability.
Impact Resistance: Drop tests from 1 meter onto concrete to ensure no cracking.
Our quality system includes in-process inspection at every production stage, final QC sampling per AQL (Acceptable Quality Level) standards, and a traceability system for batch-level records. This ensures that every order meets the same high standards.
We offer multiple packaging solutions:
Bulk Packaging: Poly bags and corrugated boxes for wholesalers.
Retail-Ready Packaging: Blister packs, display boxes, and hang tags for online sellers.
Custom Packaging: Our in-house team can design and produce packaging that aligns with your brand identity.
We ship to supermarkets, top online shop sellers, and brands worldwide. Standard production lead time is 15–25 working days. We help you choose between air freight (faster, higher cost) and sea freight (slower, lower cost) based on your timeline and budget.
