Invisible Zipper with Yarn-Dyed Finish for Caps
This invisible 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 yarn-dyed finish surface, the 5# Gauge and the packing — and held on file, which is what keeps caps 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 shrinkage that only showed up after the first wash, or a zipper puller that broke under pull test at the warehouse. Both are preventable once the specification is written down before bulk starts.
