These are fluffy, fluffy socks with cat tails. They are thick and sturdy, and warm. It's gotten cold suddenly, so how about them as room socks? They are new and unused, but there may be some loose threads. I don't think there are any noticeable stains, but since it's a personal assessment, I would appreciate it if you could understand. Your child would probably be happy to wear these at kindergarten or nursery school. Adult size. I would appreciate it if we could take our time with the transaction. (*´˘`*) Please read my profile.
