Metal Zipper for an Independent Boutique in Indonesia
An Independent Boutique approached us with a metal zipper requirement for the Indonesia 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
- Elastic that lost recovery after three washes
- An interlining that bubbled after the first press
- A zipper puller that broke under pull test at the warehouse
What we specified
| Item | Metal Zipper |
|---|---|
| Client type | An Independent Boutique |
| Market | Indonesia |
| Order volume | 10,000 pieces across 4 specifications |
| Base material | Aluminium |
| Standard size | 32 mm Width |
| Finish | Antique Brass Plating |
| Sampling rounds | 3 |
| Delivery window | 10 weeks from PO to ex-factory |
| Compliance | AATCC Test Methods |
How it was resolved
- We rebuilt the specification around Aluminium and locked the tolerance before bulk.
- The finish was moved to Brushed Silver 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 10-week window.
- Unit cost held within 4.5% of the original quotation.
- Inspection-related rejection stayed under 0.5%.
- 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.
