A white sample (unprinted structural prototype) is an exact physical mockup of your custom box cut from the intended board stock using a digital CAD sample table without printing.
### Why White Samples Save Thousands of Pounds:
1. Verifying Physical Product Fit: Guarantees your product and internal inserts fit with exact clearance tolerances before ordering thousands of units.
2. Testing Assembly & Crease Function: Checks that folding tabs lock cleanly and automatic crash-lock bases pop open smoothly.
3. Real-World Courier Drop Testing: Allows you to pack the sample with actual products and ship it via your courier network to test transit protection.
4. Eliminating Tooling Mistakes: Correcting a CAD dieline before manufacturing expensive cutting dies avoids costly production reruns.
