I bought these when my family went to Canada. I've worn them a few times at home, but there are no noticeable stains. These are hand-knitted Cowichan socks. They have high cold protection and water repellency, making them perfect for those with cold feet. They are a unisex free size. Size: 25cm-27cm (Photo 3) Height when worn: Approximately 17cm (Photo 4) Colors: White, dark brown, gray Please purchase only if you understand that these have been stored at home by a private seller. Returns are not accepted to prevent any trouble.
