Invisible Zipper for a Hotel Group in Saudi Arabia
A Hotel Group approached us with a invisible zipper requirement for the Saudi Arabia 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
- A zipper puller that broke under pull test at the warehouse
- Elastic that lost recovery after three washes
What we specified
| Item | Invisible Zipper |
|---|---|
| Client type | A Hotel Group |
| Market | Saudi Arabia |
| Order volume | 100,000 pieces across 3 specifications |
| Base material | Brass |
| Standard size | 50 mm Width |
| Finish | Yarn-Dyed Finish |
| Sampling rounds | 3 |
| Delivery window | 8 weeks from PO to ex-factory |
| Compliance | CPSIA |
How it was resolved
- We rebuilt the specification around Brass and locked the tolerance before bulk.
- The finish was moved to Pearlescent Coating 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 8-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
Lock the material standard before sampling. Once the base changes, every downstream approval has to be redone and the calendar slips.
