Case Study: Custom Old Fashioned Swimming Cap for an Amazon Private Label Seller in Japan

Old Fashioned Swimming Cap for an Amazon Private Label Seller in Japan

An Amazon Private Label Seller approached us with a old fashioned swimming cap 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

• Unclear responsibility when a defect shows up after washing
• No reliable way to track a order once it enters production
• Packaging that arrives crushed and unsellable

What we specified

How it was resolved

1. We rebuilt the tech pack around French Terry and locked shrinkage allowance before grading.
2. Decoration was moved to Pleating after strike-off tests showed better wash durability.
3. A pre-production sample was approved and retained as the golden reference.
4. Production ran with in-line inspection and a mid-run photo report.
5. Cartons were packed to the client's own barcode and size ratio specification.

Result

• 800 pieces delivered inside the 6-week window.
• Unit cost held within 3.0% 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

Fix the size ratio early. Changing the ratio after cutting starts is the single most expensive change a client can request.
