Metal Button for a Startup Apparel Label in Poland
A Startup Apparel Label approached us with a metal button requirement for the Poland market. The brief was specific: a defined look, a hard launch date and a unit cost that had to survive freight and duty. This case study records what was specified, what went wrong in sampling and how the bulk order was delivered.
The challenge
- Lead time quoted without the plating or dyeing sub-process
- Cartons packed to the factory ratio instead of the buyer's size ratio
- A spec that lived in an email instead of a tech pack

What we specified
| Item | Metal Button |
|---|---|
| Client type | A Startup Apparel Label |
| Market | Poland |
| Order volume | 10,000 pieces across 6 specifications |
| Base material | Zinc Alloy |
| Standard size | 9 mm Width |
| Finish | Nickel-Free Electroplating |
| Sampling rounds | 3 |
| Delivery window | 4 weeks from PO to ex-factory |
| Compliance | AATCC Test Methods |
How it was resolved
- We rebuilt the specification around Zinc Alloy and locked the tolerance before bulk.
- The finish was moved to Black Nickel Finish after strike-off tests showed better durability.
- A pre-production sample was approved and retained as the golden reference.
- Production ran with in-line inspection and a mid-run photo report.
- Cartons were packed to the client's own barcode and ratio specification.

Result
- 10,000 pieces delivered inside the 4-week window.
- Unit cost held within 2.0% of the original quotation.
- Inspection-related rejection stayed under 2.0%.
- The specification is now on file, so reorders reproduce the approved sample.
What we would repeat
Approve a pre-production sample made from the actual bulk base material. Substitute material behaves differently in finishing.
