Polyester Lobster Clasp for Bras — Specification, Uses and Sourcing Notes
Polyester Lobster Clasp for Bras: Specification, Uses and Sourcing Notes
Polyester Lobster Clasp is the version buyers specify for bras when the base material is fixed by performance rather than by price. This entry sets out what the material actually changes, which specification to write into the tech pack, and where the cost sits — the three questions that decide whether the item passes bulk approval.
What it is
Polyester gives lobster clasp its weight-to-strength ratio. In practice that means the trim behaves differently in cutting, in finishing and in wear: tighter tolerance is needed on the finished dimension. Buyers who specify the material up front avoid the most common failure — an item that looks right on the sample card and behaves differently in bulk.

How to specify it
- Name the base material in the tech pack, not just the item.

- Approve a counter sample made from the actual bulk base material.
- Order the test report against the standard your market requires.
- Retain a golden sample at the factory and a second one with you.
