Resin Button for a Logistics Company in Norway
A Logistics Company approached us with a resin button requirement for the Norway 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 zipper puller that broke under pull test at the warehouse
- Cartons packed to the factory ratio instead of the buyer's size ratio
What we specified
| Item | Resin Button |
|---|---|
| Client type | A Logistics Company |
| Market | Norway |
| Order volume | 100,000 pieces across 6 specifications |
| Base material | Copper |
| Standard size | 10# Gauge |
| Finish | Rainbow Iridescent Finish |
| Sampling rounds | 4 |
| Delivery window | 5 weeks from PO to ex-factory |
| Compliance | California Prop 65 |
How it was resolved
- We rebuilt the specification around Copper and locked the tolerance before bulk.
- The finish was moved to Rose Gold 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 5-week window.
- Unit cost held within 1.5% 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
Approve a pre-production sample made from the actual bulk base material. Substitute material behaves differently in finishing.
