Piping Cord with Black Nickel Finish for Socks
This piping cord is supplied to a written specification so that reorders match the approved sample. The product spec is fixed at quotation stage — base material, the black nickel finish surface, the 8# Gauge and the packing — and held on file, which is what keeps socks 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 a spec that lived in an email instead of a tech pack, 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.
