Invisible Zipper with Black Nickel Finish for Evening Wear
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 black nickel finish surface, the 10# Gauge and the packing — and held on file, which is what keeps evening wear 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 trim that passed sampling but failed in-line because it was never cycle tested, or lead time quoted without the plating or dyeing sub-process. Both are preventable once the specification is written down before bulk starts.

FAQ
What happens if a bulk lot fails inspection?
The lot is reworked or remade at our cost. Inspection reports are shared before the balance payment is due.
Can you handle our own artwork or tooling?
Yes. Artwork files or existing tooling can be used; we confirm tolerances in writing before the first production run.
Do you hold stock for reorders?
Approved specifications are kept on file and, for repeat programmes, base material can be reserved against a rolling forecast.
How long does sampling take?
10 working days for the first sample, with 5 days per revision round. Plated or dyed-to-match items add a few days.
