Invisible Zipper with Nickel-Free Electroplating 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 nickel-free electroplating surface, the 3# 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 an interlining that bubbled after the first press, or a compliance document that arrived after the goods were already shipped. 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 match a physical sample?
Yes. Send the reference and we reverse engineer the specification, then produce a counter sample for approval before any bulk commitment.
Which compliance documents do you provide?
ISO 12947 Abrasion Resistance documentation is issued with the shipment. Test reports can be ordered against any additional standard you nominate.
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.
Share the programme details and we will propose two alternatives — one optimised for unit cost, one for lead time — and let you choose.
