Shell Button for an Independent Boutique in Finland
An Independent Boutique approached us with a shell button requirement for the Finland 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
- Lead time quoted without the plating or dyeing sub-process
- A spec that lived in an email instead of a tech pack
- A trim that passed sampling but failed in-line because it was never cycle tested
What we specified
| Item | Shell Button |
|---|---|
| Client type | An Independent Boutique |
| Market | Finland |
| Order volume | 100,000 pieces across 4 specifications |
| Base material | Iron |
| Standard size | 15 mm Width |
| Finish | Yarn-Dyed Finish |
| Sampling rounds | 4 |
| Delivery window | 10 weeks from PO to ex-factory |
| Compliance | ISO 12947 Abrasion Resistance |
How it was resolved
- We rebuilt the specification around Iron and locked the tolerance before bulk.
- The finish was moved to Chrome 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 10-week window.
- Unit cost held within 3.0% of the original quotation.
- Inspection-related rejection stayed under 0.5%.
- 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.
