These warm socks are made with plenty of YAK, a high-quality material comparable to cashmere, and are beloved in the cold region of Mongolia. They are incredibly warm socks with a comfortable, non-itchy feel. The wool material is breathable and has excellent moisturizing properties, making it ideal for the cold season. This is a size 23-25 cm. Many people repurchase these, and they are easy to care for. Please comment if you are a repeat customer. You will receive a 50 yen discount per pair. I have other colors available. Please take a look. If you need a gift bag, please let me know in the comments, and I will provide one free of charge. Thank you.
