Jeans Button for a Promotional Product Agency in Czechia
A Promotional Product Agency approached us with a jeans button requirement for the Czechia 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
- A zipper puller that broke under pull test at the warehouse
- Elastic that lost recovery after three washes
- Shrinkage that only showed up after the first wash
What we specified
| Item | Jeans Button |
|---|---|
| Client type | A Promotional Product Agency |
| Market | Czechia |
| Order volume | 20,000 pieces across 6 specifications |
| Base material | Rubber |
| Standard size | 32 mm Width |
| Finish | Nickel-Free Electroplating |
| Sampling rounds | 3 |
| Delivery window | 8 weeks from PO to ex-factory |
| Compliance | ISO 105 Colour Fastness |
How it was resolved
- We rebuilt the specification around Rubber and locked the tolerance before bulk.
- The finish was moved to UV Printing 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
- 20,000 pieces delivered inside the 8-week window.
- Unit cost held within 3.0% 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
Lock the material standard before sampling. Once the base changes, every downstream approval has to be redone and the calendar slips.
