I purchased these for my daughter at Shimamura for 1500 yen and kept them in storage. However, she outgrew them while they were being stored, so I am now listing them for sale. Boa slip-ons Size: 20cm The inside is lined with boa, so I think they will be warm. They are new and unused, but have been stored at home for a long time. Therefore, please refrain from purchasing if you are sensitive about this. m(_ _)m
