Please read my profile before purchasing. I believe this is the type of cord used for Chinese knotting, decorative knotting, and stringing beads, used to create decorations, accessories, and straps. ◯ Thickness: Approximately 1mm to 1.5mm ◯ Length: Unknown ◯ Shape: Roll It's a cord with a satin-like sheen. There are 10 colors in total, all with beautiful gradations. I have two sets available. If you would like two sets, please send me a message. This is a set product, so I cannot accept requests for individual sales. Thank you for your understanding. I've set the price low because the length is unknown. Shipping will be from the post office. I have other items for sale, so please take a look if you'd like. Thank you for viewing.
