Invisible Zipper for a Bridal Studio in Thailand
A Bridal Studio approached us with a invisible zipper requirement for the Thailand 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
- MOQ that was quoted per colourway rather than per style
- Shrinkage that only showed up after the first wash
- Elastic that lost recovery after three washes
What we specified
| Item | Invisible Zipper |
|---|---|
| Client type | A Bridal Studio |
| Market | Thailand |
| Order volume | 100,000 pieces across 2 specifications |
| Base material | POM Plastic |
| Standard size | 12 mm Width |
| Finish | Brushed Silver Finish |
| Sampling rounds | 2 |
| Delivery window | 8 weeks from PO to ex-factory |
| Compliance | CPSIA |
How it was resolved
- We rebuilt the specification around POM Plastic and locked the tolerance before bulk.
- The finish was moved to Nickel-Free Electroplating 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 4.5% of the original quotation.
- Inspection-related rejection stayed under 1.0%.
- The specification is now on file, so reorders reproduce the approved sample.
What we would repeat
Approve a pre-production sample made from the actual bulk base material. Substitute material behaves differently in finishing.
