Closed-End Zipper with Sandblasted Finish for Shirts
This closed-end zipper is supplied to a written specification so that reorders match the approved sample. The product spec is fixed at quotation stage — base material, the sandblasted finish surface, the 8# Gauge and the packing — and held on file, which is what keeps shirts 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 cartons packed to the factory ratio instead of the buyer's size ratio, or a trim that passed sampling but failed in-line because it was never cycle tested. Both are preventable once the specification is written down before bulk starts.
