Sew-On Button for a Home Textile Brand in Spain
A Home Textile Brand approached us with a sew-on button requirement for the Spain 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
- MOQ that was quoted per colourway rather than per style
- Cartons packed to the factory ratio instead of the buyer's size ratio
What we specified
| Item | Sew-On Button |
|---|---|
| Client type | A Home Textile Brand |
| Market | Spain |
| Order volume | 50,000 pieces across 3 specifications |
| Base material | Silicone |
| Standard size | 15 mm Width |
| Finish | UV Printing |
| Sampling rounds | 4 |
| Delivery window | 8 weeks from PO to ex-factory |
| Compliance | ISO 12947 Abrasion Resistance |
How it was resolved
- We rebuilt the specification around Silicone and locked the tolerance before bulk.
- The finish was moved to Black Nickel 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
- 50,000 pieces delivered inside the 8-week window.
- Unit cost held within 1.5% of the original quotation.
- Inspection-related rejection stayed under 1.5%.
- 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.
