Pearl Button for an Independent Boutique in Hong Kong
An Independent Boutique approached us with a pearl button requirement for the Hong Kong 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
- Shrinkage that only showed up after the first wash
- A spec that lived in an email instead of a tech pack
What we specified
| Item | Pearl Button |
|---|---|
| Client type | An Independent Boutique |
| Market | Hong Kong |
| Order volume | 100,000 pieces across 4 specifications |
| Base material | POM Plastic |
| Standard size | 12 mm Width |
| Finish | Epoxy Doming |
| Sampling rounds | 4 |
| Delivery window | 5 weeks from PO to ex-factory |
| Compliance | BSCI |
How it was resolved
- We rebuilt the specification around POM Plastic and locked the tolerance before bulk.
- The finish was moved to Yarn-Dyed 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
- 100,000 pieces delivered inside the 5-week window.
- Unit cost held within 2.0% 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
Keep one accountable owner on both sides. Most delays come from hand-offs, not from machines.
