Invisible Zipper with Gunmetal Finish for Backpacks
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 gunmetal finish surface, the 9 mm Width and the packing — and held on file, which is what keeps backpacks 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 compliance document that arrived after the goods were already shipped, or a zipper puller that broke under pull test at the warehouse. Both are preventable once the specification is written down before bulk starts.

FAQ
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.
Which compliance documents do you provide?
REACH SVHC Screening documentation is issued with the shipment. Test reports can be ordered against any additional standard you nominate.
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.
How long does sampling take?
7 working days for the first sample, with 3 days per revision round. Plated or dyed-to-match items add a few days.
