O-Ring for an Independent Boutique in Denmark
An Independent Boutique approached us with a o-ring requirement for the Denmark 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
- Shade drift between the approved lab dip and the bulk lot
- Shrinkage that only showed up after the first wash
What we specified
| Item | O-Ring |
|---|---|
| Client type | An Independent Boutique |
| Market | Denmark |
| Order volume | 50,000 pieces across 2 specifications |
| Base material | Genuine Leather |
| Standard size | 5# Gauge |
| Finish | Pearlescent Coating |
| Sampling rounds | 3 |
| Delivery window | 8 weeks from PO to ex-factory |
| Compliance | ISO 105 Colour Fastness |
How it was resolved
- We rebuilt the specification around Genuine 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
- 50,000 pieces delivered inside the 8-week window.
- Unit cost held within 2.0% 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.
