Bra Ring and Slider for an Amazon Private Label Seller in Sweden
An Amazon Private Label Seller approached us with a bra ring and slider requirement for the Sweden 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
- Cartons packed to the factory ratio instead of the buyer's size ratio
- Reorders that quietly changed supplier and changed the hand feel

What we specified
| Item | Bra Ring and Slider |
|---|---|
| Client type | An Amazon Private Label Seller |
| Market | Sweden |
| Order volume | 5,000 pieces across 2 specifications |
| Base material | Silicone |
| Standard size | 25 mm Width |
| Finish | Rainbow Iridescent Finish |
| Sampling rounds | 2 |
| Delivery window | 4 weeks from PO to ex-factory |
| Compliance | REACH SVHC Screening |
How it was resolved
- We rebuilt the specification around Silicone and locked the tolerance before bulk.
- The finish was moved to Powder 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
- 5,000 pieces delivered inside the 4-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
Keep one accountable owner on both sides. Most delays come from hand-offs, not from machines.
