Kids Gym Fitness Set for a Logistics Provider in Japan
A Logistics Provider approached us with a kids gym fitness set requirement for Japan. The brief was specific: a defined look, a hard launch date and a unit cost that had to survive shipping and duty. This case study records what was specified, what went wrong in sampling and how the bulk order was delivered.
The challenge
- Packaging that arrives crushed and unsellable
- Color drift between lab dips and bulk fabric
- Unclear responsibility when a defect shows up after washing
What we specified
| Product | Kids Gym Fitness Set |
|---|---|
| Client type | A Logistics Provider |
| Market | Japan |
| Order volume | 5,000 pieces across 6 colourways |
| Base fabric | Softshell |
| Decoration | Bonding Construction |
| Size range | Custom grading |
| Sampling rounds | 2 |
| Delivery window | 5 weeks from PO to ex-factory |
How it was resolved
- We rebuilt the tech pack around Softshell and locked shrinkage allowance before grading.
- Decoration was moved to Bonding Construction after strike-off tests showed better wash 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 size ratio specification.
Result
- 5,000 pieces delivered inside the 5-week window.
- Unit cost held within 2.0% of the original quotation.
- Return rate linked to fit or workmanship 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 from the actual bulk fabric. Proto cloth behaves differently in cutting and washing.
