This is a design of a wire group. When people use a household sewing thread, they will always let the coils roll inadvertently. The colorful clews are like a little pig that rolls round, and they line up in a team to roll on the ground. Every use of the coils consumes the "fat" of the piglets. I hope that such a small design point can make the monotonous coils become full of vitality and appeal, so that when the user sews clothes or smashes the thread, they are no longer upset, but smile.
