Size Label for a School Uniform Buyer in South Korea
A School Uniform Buyer approached us with a size label 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
- Cartons packed to the factory ratio instead of the buyer's size ratio
- A compliance document that arrived after the goods were already shipped
- A spec that lived in an email instead of a tech pack
What we specified
| Item | Size Label |
|---|---|
| Client type | A School Uniform Buyer |
| Market | South Korea |
| Order volume | 100,000 pieces across 4 specifications |
| Base material | PU Leather |
| Standard size | 20 mm Width |
| Finish | Epoxy Doming |
| Sampling rounds | 4 |
| Delivery window | 10 weeks from PO to ex-factory |
| Compliance | ISO 105 Colour Fastness |
How it was resolved
- We rebuilt the specification around PU Leather and locked the tolerance before bulk.
- The finish was moved to Brushed Silver 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 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
Lock the material standard before sampling. Once the base changes, every downstream approval has to be redone and the calendar slips.
