Reverse Coil Zipper for a Fast Fashion Retail Chain in Italy
A Fast Fashion Retail Chain approached us with a reverse coil zipper requirement for the Italy 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
- Reorders that quietly changed supplier and changed the hand feel
- A zipper puller that broke under pull test at the warehouse
What we specified
| Item | Reverse Coil Zipper |
|---|---|
| Client type | A Fast Fashion Retail Chain |
| Market | Italy |
| Order volume | 20,000 pieces across 3 specifications |
| Base material | Aluminium |
| Standard size | 6 mm Width |
| Finish | Nickel-Free Electroplating |
| Sampling rounds | 3 |
| Delivery window | 4 weeks from PO to ex-factory |
| Compliance | BSCI |
How it was resolved
- We rebuilt the specification around Aluminium and locked the tolerance before bulk.
- The finish was moved to Antique Brass Plating 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 4-week window.
- Unit cost held within 1.5% 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
Keep one accountable owner on both sides. Most delays come from hand-offs, not from machines.
