Buttonhole Elastic for a School Uniform Buyer in the Netherlands
A School Uniform Buyer approached us with a buttonhole elastic requirement for the the Netherlands 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
- Reorders that quietly changed supplier and changed the hand feel
- An interlining that bubbled after the first press
- Shrinkage that only showed up after the first wash

What we specified
| Item | Buttonhole Elastic |
|---|---|
| Client type | A School Uniform Buyer |
| Market | the Netherlands |
| Order volume | 100,000 pieces across 3 specifications |
| Base material | Ceramic |
| Standard size | 9 mm Width |
| Finish | Sandblasted Finish |
| Sampling rounds | 4 |
| Delivery window | 5 weeks from PO to ex-factory |
| Compliance | ISO 105 Colour Fastness |
How it was resolved
- We rebuilt the specification around Ceramic 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
- 100,000 pieces delivered inside the 5-week window.
- Unit cost held within 3.0% 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
Approve a pre-production sample made from the actual bulk base material. Substitute material behaves differently in finishing.
