These are Fukusuke tabi socks. 22.5cm 4 hooks The inside is flannel (for autumn and winter) Wide width 100% cotton Not a stretch material. Stored at home, new and unused. Since some time has passed, I've marked them as "Like new." Unopened. (I haven't inspected the inside. There appears to be no dirt on the parts visible from the outside.) I will ship them via post, with rain protection. I look forward to your purchase if you understand the above. Thank you for looking.
