Thank you for looking. This is a set of pump socks. I am listing these on behalf of an acquaintance. They are unused, but were not in individual bags. I don't remember when they were purchased, so please assume they have been stored by an amateur for a long time. The size is not clearly marked, so I don't know for sure, but looking at other items in this listing, they are all between 23cm and 25cm, so I believe these four pairs are also in that range. ⚠️ Please understand and agree to the fact that they do not have individual bags, are stored by an amateur, and the size is unknown before considering them. ⚠️ Please refrain from purchasing if you are sensitive. ⚠️ Due to amateur photography, there may be slight differences in color between the actual product and the photos. ⚠️ When doing business with me, please check my profile for important requests and other information before considering a purchase.
