I'm decluttering my sewing notions! My family used to do subcontracting for ready-to-wear clothing and other small bag manufacturers. I'm not sure how these chains were used. The chain at the bottom of the image is about 1 meter long and 10mm wide. The chain at the top of the image is about 22cm long and 5mm-10mm wide. If you purchase these with other items I have listed, I will discount the price by the shipping cost. Instant purchase is welcome!
