The first question a buyer asks after sending a wallet concept to a factory is rarely about price. It is about feasibility. The second, often after a week of silence, is: "Why is this taking so long?" The answer to both usually sits in the same place — the quality and completeness of the design files you sent.
Most custom wallet projects stall not because the factory lacks capability, but because the file package is incomplete. Renders without dimensions. Logos saved at 72 DPI. Color names like "dark blue" instead of Pantone codes. These gaps force manufacturers to make assumptions, leading to re-quoting, re-prototyping, and delays that could have been avoided with a proper technical package.
This guide covers physical wallet manufacturing — metal, leather, plastic, and hybrid constructions. Not software wallets. You will learn exactly which files you need to prepare, which formats factories actually use, and how to structure your package for faster quotes and smoother production.
---
A complete file package is the single fastest way to shorten the time between your first inquiry and your first sample. In manufacturing, incomplete design files routinely add two to four weeks to lead times. Every round of "can you clarify this dimension?" consumes days.
When a buyer sends only a product render and a logo, the manufacturer must interpret the construction method, guess at material thickness, and estimate tolerances. The quote they return is a guess, not a price. When actual production files arrive later, the price changes. The buyer feels misled; the factory feels frustrated.
A complete file package tells the factory exactly what to build, how to build it, and what standard to measure against. The quote becomes accurate, the prototype matches expectations, and production runs without surprises.
Concept art is for inspiration. Production files are for manufacturing. A mood board with beautiful renders tells the factory what you want it to look like. A STEP file with dimensioned drawings tells the factory how to machine it. Both are useful, but only one is actionable.
Manufacturers build from technical data, not images. If you send only renders, the factory must reverse-engineer your intent, which introduces error. Dimensioned drawings, material specifications, and finish requirements allow the factory to build exactly what you designed.
Your files define the Acceptable Quality Limit (AQL). If you specify a ±0.1mm tolerance for a CNC-machined aluminum wallet, the factory knows what passes inspection. If you specify "silver" without an anodizing code, the factory picks a shade, and you may reject it. Clear files prevent disputes over color, dimensions, and finish.

Every custom wallet project requires files from several categories. The exact mix depends on material and manufacturing process, but the core structure is consistent.
These files cover logos, engravings, printing, and embossing.
Vector files: AI, EPS, CDR. Required for laser engraving, debossing, and any process where a machine cuts or marks a line. Vector files scale infinitely without losing quality.
Raster files: PSD, TIFF, PNG. Used for pad printing, UV printing, and any process that deposits ink. They must be high-resolution — minimum 300 DPI at actual print size.
Use Pantone (PMS) codes for physical color matching. CMYK is acceptable for print, but PMS is more precise. Hex codes are for screens only. For embossing and debossing, include safe zone requirements — the design needs clearance from edges and hardware to avoid distortion during pressing.
These files define the physical structure of the wallet — its shape, thickness, and internal cavities.
STEP (.stp) is the universal standard for CNC machining and mold making. It works across all CAD platforms.
IGES (.igs) is an older format, still accepted by many factories.
SolidWorks (.sldprt) is native to that software; only send it if the factory uses SolidWorks.
DWG/DXF are 2D formats used for cutting paths and flat patterns.
For metal wallets, STEP files drive CNC programming. For plastic wallets, they drive injection mold design. For leather wallets, DXF files drive laser cutting of patterns.
This is where the "what" becomes the "how." Two documents matter most:
BOM (Bill of Materials): A complete list of every component — shell material, lining, rivets, magnets, RFID blocking layer, stitching thread. Each item needs a specification: material grade, size, quantity.
CMF (Color, Material, Finish): The specification of what each surface looks and feels like. Material grade (6061-T6 aluminum vs. 5052), surface finish (anodizing, brushing, polishing), and color codes all belong here.
Include hardware specs too: magnet type (N35 vs. N52), screw size, thread type. For metal parts, specify dimensional tolerances — ±0.1mm is standard for CNC, ±0.2mm for casting.
Retail packaging requires its own file set. Die-cut lines for boxes typically come as AI or PDF with proper bleed. Barcode specs (UPC/EAN) need correct sizing and placement. Regulatory labeling — material composition, RFID warnings, country of origin — must meet destination market requirements.
Digital files communicate geometry and color. Physical samples communicate texture, weight, and hand-feel. A crude prototype made of cardboard tells the factory more about your intended thickness than a perfect render does. If you have a reference sample — even a competitor's product you want to improve upon — send it. A "golden sample" representing your exact target is even better.

Different materials require different file priorities. A metal wallet is machined from a solid block; a leather wallet is cut from a sheet.
Metal wallets require the most rigorous file package. You need:
STEP files for CNC machining — the machine needs a solid model to generate toolpaths.
DXF files for any 2D cutting operations.
Vector files for laser engraving logos or patterns.
Key specifications: wall thickness (typically 1.0–2.0mm for aluminum cardholders), chamfer angles, and surface finish. Anodizing colors are specified by industry codes — a specific bronze shade might be a custom formulation rather than a standard Pantone match. Metal requires tighter tolerances than leather because there is no give in the material. A card slot that is 0.2mm too narrow will not fit a card.
Leather introduces a different set of requirements. You need:
DXF files for laser cutting leather panels — these are 2D flat patterns.
Stitching specifications — thread type (polyester vs. nylon), thread thickness, and SPI (stitches per inch). Standard is 6–8 SPI for most wallet construction.
Edge painting color — if the wallet has painted edges, specify the exact color and finish.
Leather thickness is measured in ounces (1 oz = 1/64 inch). A typical wallet uses 2.0–3.0 oz leather for interior pockets and 3.0–4.0 oz for exterior panels. Specify this in your BOM.
One critical file element for leather goods: the "unfolded" or "layflat" view. A 3D wallet shape must be translated into 2D cutting patterns. Factories also create "nested layouts" — arranging patterns on a leather hide to minimize waste. This is a cost-saving step you should request.
Plastic wallets are injection molded, which requires:
3D CAD files (STEP preferred) for mold design.
2D drawings with gate location, draft angles, and wall thickness specifications.
Draft angles matter — typically 1–2 degrees for textured surfaces, 0.5–1 degree for smooth. Without adequate draft, the part sticks in the mold.
For RFID-blocking wallets, specify the shielding material and its placement in the BOM. Common options are aluminum foil layers, conductive fabric, or metal plates. Each has different thickness and flexibility characteristics that affect the wallet's design.

You do not need to be a CAD expert to prepare a proper file package. You need to follow a structured process.
Write a product brief before touching any design software. Answer these questions:
What is your target retail price? This determines material options.
What functionality is required? RFID blocking, card capacity (4 cards vs. 12), money clip, coin pocket?
What is your target weight and thickness?
What aesthetic direction — minimalist metal, classic leather, tactical nylon?
This brief guides which files are critical. A thin aluminum cardholder needs precision CAD files. A leather bifold needs pattern files and stitching specs.
There are two paths here. Option A: hire an industrial designer to create full technical drawings and 3D CAD. Industry rates for wallet design range from $500 to $5,000 depending on complexity. Option B: work from a manufacturer's existing template. Many OEM factories have catalog products you can customize — change the logo, colors, and materials. This is faster and cheaper, but limits you to existing structures.
Whichever path you choose, ensure the drawings include dimension lines, tolerances, and surface finish symbols. These annotations are what make a drawing "manufacturable."
File naming matters more than most buyers realize. A folder full of "final_v2_FINAL_reallyfinal.ai" files wastes everyone's time. Use a consistent convention: ProjectName_PartNumber_Version_Date. Example: GSTAR_MetalCardholder_V3_2024.10.01.step.
When transferring files, use a method that preserves integrity — WeTransfer, Google Drive, or the manufacturer's FTP. For sensitive designs, sign an NDA first and use a secure transfer method.
Your file package is not finished after the first submission. It evolves. The first prototype (P1) reveals fit issues, finish problems, and usability concerns. You revise the files. P2 addresses those issues. Sometimes P3 is needed. Budget for this iteration — it is not a failure, it is the process.

These errors appear constantly in real projects. Avoid them and you will save weeks.
A 72 DPI logo pulled from a website will produce a blurry engraving or print. The rule is simple: minimum 300 DPI at actual print size. If your logo will be 20mm wide, the file must be 300 DPI at 20mm width. If you only have a low-res version, ask a designer to redraw it as a vector.
"Dark blue" is subjective. "Pantone 294C" is specific. For anodized aluminum, even Pantone may not match — anodizing is a chemical process that produces colors differently than printing. Work with your manufacturer to select an anodizing reference. For printed elements, always provide PMS codes.
If you do not specify tolerances, the factory defaults to industry standards: ±0.2mm for plastic, ±0.1mm for CNC metal. These may not match your fit requirements. If you need a card slot to fit a standard credit card (0.76mm thick) with a specific tightness, you must specify the tolerance.
For leather goods, this is the most common mistake. A beautiful 3D render does not tell the factory how to cut the leather panels. You must provide a 2D flat pattern — or explicitly ask the factory to create one from your 3D model. This is a design step, not a manufacturing step, and it affects material yield and cost.
---
Your file package is only as good as the factory's ability to interpret it. The manufacturer's engineering team is part of the equation.
Does the factory have in-house engineers who can review and redraw files? This is standard for established OEM manufacturers. If the factory cannot provide a DFM (Design for Manufacturing) review — a formal assessment of whether your design can be produced as specified, with suggestions for improvement — treat that as a red flag.
A good DFM review catches problems before tooling is cut. It might suggest increasing a wall thickness from 1.0mm to 1.2mm to avoid warping, or changing a sharp internal corner to a radius to improve CNC machining speed.
Ask these questions before you send anything:
"Can you provide a DFM review of my files before quoting?"
"What is your standard file acceptance format?"
"Do you offer a prototype service based on my files?"
"What is your typical prototype lead time?"
Your design files are intellectual property. Industry standard practice: sign an NDA before sharing 3D CAD. Any reputable manufacturer will agree without hesitation. If a factory refuses to sign an NDA, do not share your files.

The standards described above — STEP files for CAD, 300 DPI for raster, PMS codes for color, DFM reviews before quoting — are not theoretical. They are the operating procedures of established manufacturers. As a manufacturer with 13+ years of experience producing RFID wallets, key organizers, and card holders, GSTAR (Gstar Technology (Shenzhen) Co., Ltd.) works within these exact standards.
Our in-house engineering team reviews every file package for manufacturability before we provide a quote. We accept STEP, IGES, DWG, DXF, AI, PDF, and high-resolution PSD files. If your files have issues — insufficient tolerance, missing draft angles, low-resolution logos — we flag them upfront and suggest corrections. This DFM check is free and happens before any commitment.
For buyers without 3D files, we offer a practical alternative: OEM solutions based on our existing catalog templates. You select a base design, specify color, material, and logo, and our engineers generate the production files for you. This is the fastest path to a custom product for brands without in-house design capacity.
Our file-handling process connects directly to production capability. With in-house CNC machining and a monthly production capacity of 300,000+ units, we are equipped to move from your file package to mass production efficiently. Our engineering team ensures your specifications translate accurately into the physical product — the same way the standards in this guide describe.

Frequently Asked Questions
Digital Apple Wallet passes use the .pkpass format, created with an Apple Pass Certificate. This is unrelated to physical wallet manufacturing. If your project involves both a physical wallet and a digital companion pass, they require completely separate file packages.
The OEM route is your answer. Choose an existing template from a manufacturer's catalog, specify your color, material, and logo, and the manufacturer creates the production files. Most manufacturers provide this as a value-added service.
Technically, a factory can reverse-engineer a product from photos, but this raises two problems. First, IP infringement — copying a competitor's design can expose you to legal liability. Second, photos lack dimensions and internal construction details. A better approach: reverse-engineer with measured dimensions and create your own technical drawings.
For raster files, 300 DPI at the physical size of the logo. For vector files (AI, EPS), resolution is irrelevant — vector files scale infinitely. Always prefer vector for engraving and embossing, because the machine follows the vector path directly.
Industry standard is 24–72 hours for a preliminary quote, depending on file complexity. A complete file package speeds this up significantly.
This question is outside the scope of physical wallet manufacturing. It relates to digital cryptocurrency wallets, which are software applications. This article covers physical wallet production files. For digital wallet security questions, consult a cybersecurity resource.
Development costs vary by complexity. Prototyping typically ranges from $200 to $2,000. Mold and tooling for plastic injection runs $500 to $5,000. Per-unit costs depend on material and order quantity. A complete, accurate file package reduces development cost by minimizing iteration rounds.

Product Brief — Word or PDF document defining target price, functionality, and aesthetic.
2D Artwork — AI or EPS vector files plus high-resolution PNG (300 DPI).
3D CAD — STEP or IGES files for structural design.
2D Technical Drawing — PDF or DWG with dimensions and tolerances.
BOM — Excel or CSV listing every component and material.
CMF Specification Sheet — Color codes, material grades, finish requirements.
Packaging Die-Line — AI or PDF with bleed and barcode placement.
Logo Files — Vector preferred; high-res raster as backup.
Reference Sample — Physical sample or detailed photos with a scale reference.
Target Price & MOQ — So the manufacturer can advise on material and process trade-offs.
---
Choose OEM customization if: You have a clear brand identity but limited design resources. You want faster development and lower upfront costs. You are comfortable selecting from proven templates and modifying colors, materials, and logos. This path suits first-time importers and brands launching their first wallet product.
Choose full custom design if: You have a unique structural concept that existing products do not cover. You have design resources or budget for an industrial designer. You need specific functionality — unusual card capacity, proprietary RFID shielding, a distinctive opening mechanism. This path suits established brands with design teams and higher budgets.
