Shank Button with Rainbow Iridescent Finish for Sportswear
This shank 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 rainbow iridescent finish surface, the 50 mm Width and the packing — and held on file, which is what keeps sportswear 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 lead time quoted without the plating or dyeing sub-process, or elastic that lost recovery after three washes. Both are preventable once the specification is written down before bulk starts.

FAQ
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.
What is the minimum order quantity?
Standard MOQ is 500 per style per colour. Mixed colourways can be combined on the same spec if the base material is identical.
What are the payment and delivery terms?
Standard terms are a deposit with the order and the balance before shipment, under EXW / FOB / CIF / DDP as agreed.
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.
