Tack Button for an Independent Boutique in Chile
An Independent Boutique approached us with a tack button requirement for the Chile 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
- A trim that passed sampling but failed in-line because it was never cycle tested
- An interlining that bubbled after the first press

What we specified
| Item | Tack Button |
|---|---|
| Client type | An Independent Boutique |
| Market | Chile |
| Order volume | 20,000 pieces across 3 specifications |
| Base material | PU Leather |
| Standard size | 3# Gauge |
| Finish | Silicone Wash Finish |
| Sampling rounds | 4 |
| Delivery window | 10 weeks from PO to ex-factory |
| Compliance | REACH SVHC Screening |
How it was resolved
- We rebuilt the specification around PU Leather and locked the tolerance before bulk.
- The finish was moved to Anodised 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
- 20,000 pieces delivered inside the 10-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.
