This is a set of 5 pairs of socks. I bought them on SHEIN, but the wrong size was delivered, so I'm selling them. They have an "S" on the sole, so I think they are size S. They are for 2-3 year olds, 14-15cm. I have opened the package, but they are completely unused. Would they be suitable for a change of socks at nursery school, etc.? Please refrain from purchasing if you are concerned about home storage. Please note that they may be sold out on other sites.
