Resin Button for a Bag and Luggage Maker in Czechia
A Bag and Luggage Maker approached us with a resin button requirement for the Czechia 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
- Shrinkage that only showed up after the first wash
- A spec that lived in an email instead of a tech pack
- Lead time quoted without the plating or dyeing sub-process
What we specified
| Item | Resin Button |
|---|---|
| Client type | A Bag and Luggage Maker |
| Market | Czechia |
| Order volume | 100,000 pieces across 4 specifications |
| Base material | Polyester |
| Standard size | 8# Gauge |
| Finish | Epoxy Doming |
| Sampling rounds | 2 |
| Delivery window | 4 weeks from PO to ex-factory |
| Compliance | California Prop 65 |
How it was resolved
- We rebuilt the specification around Polyester 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 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.
