Open-End Zipper for a Promotional Product Agency in Turkey
A Promotional Product Agency approached us with a open-end zipper 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
- A compliance document that arrived after the goods were already shipped
- Elastic that lost recovery after three washes
- MOQ that was quoted per colourway rather than per style
What we specified
| Item | Open-End Zipper |
|---|---|
| Client type | A Promotional Product Agency |
| Market | Turkey |
| Order volume | 50,000 pieces across 6 specifications |
| Base material | Cotton |
| Standard size | 5# Gauge |
| Finish | Piece-Dyed Finish |
| Sampling rounds | 4 |
| Delivery window | 6 weeks from PO to ex-factory |
| Compliance | AATCC Test Methods |
How it was resolved
- We rebuilt the specification around Cotton 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
- 50,000 pieces delivered inside the 6-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.
