Case Study: Custom Jacket Zipper Slider for an Amazon Private Label Seller in Indonesia
Jacket Zipper Slider for an Amazon Private Label Seller in Indonesia
An Amazon Private Label Seller approached us with a jacket zipper slider requirement for Indonesia. The brief was specific: a defined look, a hard launch date and a unit cost that had to survive shipping and duty. This case study records what was specified, what went wrong in sampling and how the bulk order was delivered.
The challenge
- Inconsistent sizing between production runs
- Packaging that arrives crushed and unsellable
- Long lead times that miss the selling season

What we specified
| Product | Jacket Zipper Slider |
|---|---|
| Client type | An Amazon Private Label Seller |
| Market | Indonesia |
| Order volume | 500 pieces across 2 colourways |
| Base fabric | Corduroy |
| Decoration | Acid Wash |
| Size range | 2-12Y |
| Sampling rounds | 4 |
| Delivery window | 12 weeks from PO to ex-factory |
How it was resolved
- We rebuilt the tech pack around Corduroy and locked shrinkage allowance before grading.
- Decoration was moved to Acid Wash after strike-off tests showed better wash 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 size ratio specification.

Result
- 500 pieces delivered inside the 12-week window.
- Unit cost held within 1.5% of the original quotation.
- Return rate linked to fit or workmanship stayed under 1.0%.
- The specification is now on file, so reorders reproduce the approved sample.
What we would repeat
Keep one process owner on both sides. Most delays come from hand-offs, not from machines.
