These are Koguma-chan socks. I bought them at Akachan Honpo a year ago. I used them for my newborn. I rarely went outside, so I only wore them three times. I've washed them at home, and there's some pilling, but I think they can still be used. Please understand that they have been stored at home. If you purchase them with other items, I will offer a combined discount, so please let me know in the comments. (The 11 Cats socks have already been sold...)
