Sew-On Button with Yarn-Dyed Finish for Hats
This sew-on button is supplied to a written specification so that reorders match the approved sample. The product spec is fixed at quotation stage — base material, the yarn-dyed finish surface, the 38 mm Width and the packing — and held on file, which is what keeps hats 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
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.
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.
Which compliance documents do you provide?
ISO 14001 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.
