Lobster Clasp for a Uniform Supplier in the United States

A Uniform Supplier approached us with a lobster clasp requirement for the the United States 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

  • An interlining that bubbled after the first press
  • A compliance document that arrived after the goods were already shipped
  • Cartons packed to the factory ratio instead of the buyer's size ratio

Marketthe United States
Order volume5,000 pieces across 3 specifications
Base materialCotton
Standard size5# Gauge
FinishRose Gold Plating
Sampling rounds3
Delivery window8 weeks from PO to ex-factory
ComplianceCalifornia Prop 65

How it was resolved

  1. We rebuilt the specification around Cotton and locked the tolerance before bulk.
  2. The finish was moved to Matte Black Coating after strike-off tests showed better 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 ratio specification.

Lobster Clasp production run

Result

  • 5,000 pieces delivered inside the 8-week window.
  • Unit cost held within 4.5% of the original quotation.
  • Inspection-related rejection stayed under 1.0%.
  • The specification is now on file, so reorders reproduce the approved sample.

What we would repeat

Lock the material standard before sampling. Once the base changes, every downstream approval has to be redone and the calendar slips.
