This item has been used for several years. It was stored in a closet, but the other day I found that the front and back skins of the kokyu were torn. Although the skins are torn, the overall condition appears to be very clean upon visual inspection. I do not know the details of the materials. Size: Total length: 71cm Body: Length: 15.5cm Body: Width: 13.5cm Body: Thickness: 7.5cm I will ship it with care.
