Wooden Button for a Logistics Company in South Korea
A Logistics Company approached us with a wooden button requirement for the South Korea 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
- A trim that passed sampling but failed in-line because it was never cycle tested
- A compliance document that arrived after the goods were already shipped
- MOQ that was quoted per colourway rather than per style

What we specified
| Item | Wooden Button |
|---|---|
| Client type | A Logistics Company |
| Market | South Korea |
| Order volume | 20,000 pieces across 3 specifications |
| Base material | Genuine Leather |
| Standard size | 3# Gauge |
| Finish | Rose Gold Plating |
| Sampling rounds | 3 |
| Delivery window | 4 weeks from PO to ex-factory |
| Compliance | GRS |
How it was resolved
- We rebuilt the specification around Genuine Leather and locked the tolerance before bulk.
- The finish was moved to Pearlescent Coating 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 4-week window.
- Unit cost held within 3.0% 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.
