Please read my profile before purchasing. This is a set of durable cords for Chinese knotting, decorative knotting, and other handicrafts. It's a set of approximately 1.5mm x 5m x 10 colors. They seem to be called "B-bead cords." I am selling 7 sets at the same time. The color combinations are different, so I strongly recommend that you take a look at my other listings. Due to this being a set product, I cannot accommodate requests for individual sales. Thank you for your understanding. I have other items for sale, so please take a look if you'd like. Thank you for viewing.
