Sew-On Button for an Independent Boutique in New Zealand
An Independent Boutique approached us with a sew-on button requirement for the New Zealand 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
- Shrinkage that only showed up after the first wash
- Elastic that lost recovery after three washes
- MOQ that was quoted per colourway rather than per style
What we specified
| Item | Sew-On Button |
|---|---|
| Client type | An Independent Boutique |
| Market | New Zealand |
| Order volume | 100,000 pieces across 3 specifications |
| Base material | TPU |
| Standard size | 8# Gauge |
| Finish | Yarn-Dyed Finish |
| Sampling rounds | 2 |
| Delivery window | 10 weeks from PO to ex-factory |
| Compliance | REACH SVHC Screening |
How it was resolved
- We rebuilt the specification around TPU and locked the tolerance before bulk.
- The finish was moved to Piece-Dyed 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
- 100,000 pieces delivered inside the 10-week window.
- Unit cost held within 1.5% of the original quotation.
- Inspection-related rejection stayed under 1.5%.
- The specification is now on file, so reorders reproduce the approved sample.
What we would repeat
Keep one accountable owner on both sides. Most delays come from hand-offs, not from machines.
