Glass Pearl Button for Bags — Specification, Uses and Sourcing Notes
Glass Pearl Button for Bags: Specification, Uses and Sourcing Notes
Glass Pearl Button is the version buyers specify for bags 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
Glass gives pearl button its weight-to-strength ratio. In practice that means the trim behaves differently in cutting, in finishing and in wear: the finish has to be applied before assembly. 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.
