Tsubame Brand Silk Netting Thread Thickness: No. 1, No. 2, No. 3 Selling a set of three, one of each thickness. Although new and unused, the outer packaging has some minor stains. I have stored it at home after purchase. I bought it as the base thread for making Japanese fishing rods (wa-zao), but I am selling it because I will not be using it.
