These are children's jazz shoes purchased for 8,500 yen on the following Rakuten website: https://item.rakuten.co.jp/dancenets/ej2c/?variantId=51861&s-id=ph_pc_itemname The size is EJ2C 12W, equivalent to 18.0 cm. I purchased these in September of this year for a dance recital. I tried them on at home once, but ultimately couldn't participate in the performance, so I haven't used them. They have only been tried on at home for about 3 minutes, and have not been used otherwise. I disposed of the original box, so I will ship them in a box I have on hand.
