Sock Length: Short / Ankle I purchased these last year at Costco. This is a set of 4 colorful, fluffy socks in girly colors. They look very warm. There is a non-slip logo mark on the soles. Out of a set of 5, I used one, so this is a set of 4. (See photo 5) Size: 13-15cm Please understand that these have been stored at home before purchasing. To reduce the thickness, I will ship them disassembled, so please be aware of this. Thank you. Please refrain from purchasing if you are sensitive to such things.
