Please read the profile before purchasing. This is a set of 10 colors of approximately 2.5mm thick, glossy, satin-like cord, cut to 5 meters each. This is a set product, so individual colors cannot be sold separately, and color exchanges are not possible. The set consists of the 10 colors shown in the image. Please understand. I received this as a gift, so I don't know the details, but it appears to be cord for making Chinese knots or Asian knots. It's sturdy and has a beautiful range of colors. I have a lot of this mystery cord in stock, so I plan to list more in the future. The colors, thickness, and texture vary, so please take a look. I have other items for sale as well, so please take a look if you'd like. Thank you for viewing.
