23.0cm, slim fit, tabi socks, 4 hooks, white calico. Although it says "tabi," the Fukusuke Shoji Co., Ltd. listed on the back is no longer in business, and I don't think it's written on them now, but the inside is bleached cotton, so I think they can be used year-round. I have stored them for a long time, so I opened them to check for stains and discoloration. I could see a red mark on the upper ankle of one sock, but other than that, they feel like new tabi socks. They are unused, so I would be happy if you could use them.
