This is a set of baby socks for sale. They show signs of use, but they are still wearable. How about them for your energetic child's spare socks? I'm sorry, but the size is not clear. Compared to other socks, I've estimated them to be 9-15cm. I think they will be tight for children who are exactly 15cm. Photos taken with an iPhone. I'm not used to it, so there may be slight differences in color. I'm looking forward to bids from those who don't mind the details. Please understand that these are used items.
