Collar Stay with Matte Black Coating for Bras
This collar stay is supplied to a written specification so that reorders match the approved sample. The product spec is fixed at quotation stage — base material, the matte black coating surface, the 5# Gauge and the packing — and held on file, which is what keeps bras consistent across seasons instead of drifting with whatever the mill happens to have in stock.
The usual reason buyers come to us is not price. It is lead time quoted without the plating or dyeing sub-process, or elastic that lost recovery after three washes. Both are preventable once the specification is written down before bulk starts.
