These are stretch tabi socks. They fit snugly because they are made of stretchy material. They are the sock type without kohaze (clasps). *Although opened, they are unused. These are items with defects. This is a set of 3 pairs, but all 3 pairs are defective items. (These are defective items that were excluded during inspection) All 3 pairs have stains and loose threads. I have checked them, but there may be overlooked stains or loose threads. Please understand that these are defective items before purchasing. I am also selling on other sites, so I may delete the listing without notice. *I have a cat. Please do not purchase if you have allergies or are concerned. ◆Size: Free size 22.5-24cm ◆Material: 100% polyester ◆Color: White Shipping will be done with simple packaging. Recycled materials will be used. I cannot accommodate requests for shipping methods or specific shipping dates (such as "I want it as soon as possible" or "I want it on XX date"). Please understand that I will decline such requests after purchase. No price reduction.
