Waterproof Zipper with Mercerised Finish for Underwear
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 mercerised finish surface, the 25 mm Width and the packing — and held on file, which is what keeps underwear 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 lead time quoted without the plating or dyeing sub-process. Both are preventable once the specification is written down before bulk starts.
