Purchased around December 2017. They didn't fit my child's feet well and seemed difficult to wear, so they were only worn a few times, just to try them out. I think they are in very clean condition. Although they are clean, they have been stored for a long time, so please purchase only if you understand this. I have a cat, so please refrain from purchasing if you are concerned. I will ship via Yu-Packet Plus. I am a beginner seller, so there may be some shortcomings, but thank you for your understanding.
