Zipper Guard for a Lingerie Specialist in Turkey
A Lingerie Specialist approached us with a zipper guard requirement for the Turkey 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
- Cartons packed to the factory ratio instead of the buyer's size ratio
- A trim that passed sampling but failed in-line because it was never cycle tested
- MOQ that was quoted per colourway rather than per style
What we specified
| Item | Zipper Guard |
|---|---|
| Client type | A Lingerie Specialist |
| Market | Turkey |
| Order volume | 50,000 pieces across 3 specifications |
| Base material | Silicone |
| Standard size | 32 mm Width |
| Finish | Anodised Finish |
| Sampling rounds | 2 |
| Delivery window | 6 weeks from PO to ex-factory |
| Compliance | GB 18401 |
How it was resolved
- We rebuilt the specification around Silicone 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
- 50,000 pieces delivered inside the 6-week window.
- Unit cost held within 3.0% 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
Fix the specification count early. Adding variants after production starts is the most expensive change a client can request.
