Thank you for viewing! These socks have thick soles and heels. I've been using the same ones for my child for several years, and they're durable, so they haven't worn through yet. This is a set of 9 pairs: 6 black and 3 gray. I do not accept individual sales. If you're okay with me cutting off the tags before shipping, I can offer a 200 yen discount. 【UNIQLO / Uniqlo】 【Size: 16-20cm】 【Colors: Black, Gray】 There may be slight differences between the actual product and the images, and the colors may vary depending on your monitor. 【Condition】 Purchased in-store and stored at home, unused. Please understand that there may be oversights due to my amateur inspection. I look forward to your purchase if you understand that these are items stored at home. 【Other】 Please read my profile before purchasing. If you have any questions or concerns, feel free to comment. Items scheduled for anonymous shipping may be changed from Rakuraku to Yuuyu or vice versa. Thank you for reading to the end m(_ _)m
