Fujix King High Span Button Sewing Thread 100% Polyester #20 (For medium to heavy fabrics) One roll: 30m, New and Unused Colors: 67, 81, 322 Deep green colors. ＜From the official website＞ This is a high-strength polyester thread specifically for attaching buttons, resistant to "pulling" and "bending." It withstands harsh friction well, preventing buttons from falling off. The thread has moderate stiffness, firmly holding buttons in place. It can be widely used for sewing and other purposes, taking advantage of its thickness, strength, and durability. Due to long-term storage at home, there may be stains on the cardboard and packaging. Please judge from the photos. I think the thread itself is fine, but please be aware if you are concerned. #NodaGoods_CraftSupplies I also sell Clover, KAWAGUCHI, Kiyohara, and other craft supplies. I welcome combined shipping, so please take a look.
