Please read my profile before purchasing. I believe these are cords for making Chinese knots and decorative knots. They are satin-like, shiny, and have a smooth texture. ◯ Thickness: Approximately 2.5mm ◯ Length: Approximately 5m ◯ Other: 10 colors x 1 each I have listed 4 sets at the same time. Each set has a different color combination, so I highly recommend that you take a look at the other sets as well. This is a set product, so 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.
