Waterproof Zipper with Brushed Silver Finish for Hats
This waterproof 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 brushed silver finish surface, the 6 mm Width and the packing — and held on file, which is what keeps hats 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 shade drift between the approved lab dip and the bulk lot, or a zipper puller that broke under pull test at the warehouse. Both are preventable once the specification is written down before bulk starts.
