Hook and Eye for a Yacht Interior Studio in the United States
A Yacht Interior Studio approached us with a hook and eye requirement for the the United States 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
- Reorders that quietly changed supplier and changed the hand feel
- Shade drift between the approved lab dip and the bulk lot

What we specified
| Item | Hook and Eye |
|---|---|
| Client type | A Yacht Interior Studio |
| Market | the United States |
| Order volume | 100,000 pieces across 4 specifications |
| Base material | Brass |
| Standard size | 20 mm Width |
| Finish | Epoxy Doming |
| Sampling rounds | 4 |
| Delivery window | 6 weeks from PO to ex-factory |
| Compliance | REACH SVHC Screening |
How it was resolved
- We rebuilt the specification around Brass and locked the tolerance before bulk.
- The finish was moved to Sandblasted 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
- 100,000 pieces delivered inside the 6-week window.
- Unit cost held within 1.5% of the original quotation.
- Inspection-related rejection stayed under 2.0%.
- 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.
