TL;DR: A pre-production sample is a prototype of your bag built before bulk production begins. It allows you to verify that the factory has correctly interpreted your specifications — material, dimensions, construction, hardware, and logo — before committing to hundreds or thousands of units. Never place a bulk production order without approving a sample.
What Is a Pre-Production Sample?
A pre-production sample (also called a prototype, first sample, PP sample, or gold seal sample depending on the stage) is a physically produced version of your bag, built at the factory using the production materials and construction methods specified in your brief or tech pack.
It is the first tangible proof that the factory has understood your requirements. It is also your last, best opportunity to identify and correct problems before they are replicated across your entire order quantity.
The cost of fixing a problem at the sample stage: $0–$50 (revision request and a second sample). The cost of fixing the same problem after 200 units have been produced: $2,000–$15,000+ (replacement, rework, or loss of goods).
The Sample Development Stages
For new bag designs, the development process typically involves 2–3 sample rounds:
Round 1 — First Sample (Proto Sample): The factory builds from your brief, tech pack, or reference sample. This is a “best interpretation” of your requirements. It is rarely 100% correct on the first round and is not expected to be. Your job is to identify everything that needs to change and communicate it precisely in writing.
Round 2 — Revised Sample (Second Sample): The factory incorporates your Round 1 feedback and produces an updated version. Most straightforward designs reach 90–95% correctness at this stage.
Round 3 — Sealed Sample / Gold Seal Sample: The sample you approve as the reference standard for bulk production. A photo record of this sample (from all angles, with all hardware and logo details) is sent to both you and the factory as the agreed benchmark. Bulk production must match this sealed sample.
What a Sample Should Include
A proper pre-production sample should be built using:
- The exact material specified for bulk production (not a substitute)
- The correct hardware (not “similar” hardware from factory stock)
- Your logo is applied exactly as it will appear in production
- All interior features: pockets, dividers, key fob, zipper pulls
- All exterior features: straps (at correct length), feet, handle attachments
- Packaging is not typically included in early samples, but should be confirmed before the sealed sample stage
If the factory builds your sample in a different material than specified “to save time,” this is a red flag. The sample should represent exactly what you will receive in bulk.
How to Evaluate a Sample — The Detailed Checklist
Construction quality:
- All seams are straight, even, and with consistent spacing
- No loose threads at any seam or attachment point
- All edges finished (leather edges burnished, fabric edges bound or turned)
- Lining sits flat without puckering or bunching
- Corners and base maintain shape under moderate load
Hardware function:
- The zipper opens and closes 20 times without catching or snagging
- Magnetic snap engages and releases cleanly
- Turn-lock rotates smoothly with appropriate resistance
- All buckles and clasps open and close correctly
- Strap adjustment slides smoothly through the buckle
Logo and branding:
- Logo correctly positioned per specification
- Embossing/debossing depth consistent and even
- Metal plate edges are smooth (no sharp points or burrs)
- No misalignment, slanting, or off-center placement
Materials:
- Main material matches specification (hand feel, thickness, texture)
- Hardware finish matches specification (color, shine level)
- Lining material and color match specification
Dimensions:
- Overall dimensions within ±5mm of specification
- Strap length and drop are correct
- Interior pocket dimensions correct
Overall impression:
- Would you be proud to sell this bag at your target price?
- Would your target customer perceive this as matching the value they are paying?
How to Give Revision Feedback (The Right Way)
Clear revision feedback prevents another incorrect sample. Always provide:
- Annotated photos: Mark up the sample photos with arrows, circles, and text notes on each issue
- Specific language: “Zipper is catching at the 8cm mark from the right end — the slider feels rough,” not “the zipper is bad.”
- Priority ranking: Flag which issues are critical (must fix before bulk) versus preferred (improve if possible)
- Reference for corrections: If the issue is wrong coloring, include a Pantone reference; if a dimension is wrong, include the correct measurement
- Version date: Mark your feedback document with the date and “Revision for Sample Round 1 [style name]”
Sample Lead Time and Costs
Standard sample lead time: 7–15 business days from specification confirmation. Express sample service: Some factories offer 37-day sample production at a premium
Sample costs:
- Standard samples at most bag factories: $30–$100 per sample
- Leather bags or complex construction: $80–$250 per sample
- Many factories credit sample cost toward the first bulk production order
How many samples should you request? Order 2 samples per round — one to evaluate and one to retain as a physical record. If you are developing multiple colorways, confirm that the approved design in one color translates correctly to alternate colors before bulk production.
FAQ
Q: Can I approve production based on factory catalog photos instead of a sample? A: No. Catalog photos are marketing materials. They may represent ideal samples that are not representative of production quality, or they may be retouched. Always require a physical sample built to your specification.
Q: The factory says they have produced this design many times before and do not need a sample. Should I agree? A: No. A factory’s prior production history does not guarantee that your specific configuration — your material choice, your hardware, your logo, your dimensions — will be executed correctly. Insist on a sample.
Q: How many revision rounds are normal before approving for bulk? A: Two to three rounds are normal. If you are on Round 5 and the sample is still significantly wrong, this is a signal that either the factory is not capable of executing your design or your specifications need to be communicated differently.
