Sanrio Marron Cream Kappogi (apron) (^^) The inside of the back is boa material, so it looks warm. Size: M-L Flat measurement length: Approximately 77 cm (Since this is amateur measurement, there may be some errors) Although it is new and unused, it was a product displayed in the store, and there is a small black thread wrapped around the shoulder area from the time of purchase.
