These are FUKUSUKE's fireplace Tabix socks that I purchased some time ago. They are unused and have been stored for a while, but are in good condition. They are made of heat-retaining materials (acrylic, nylon, wool) that are great for preventing cold feet. The toes are divided in two, just like tabi socks, so they are useful for wearing zori sandals with thongs. The size is 27-28cm. Please consider them if you are interested.
