Sanrio Shinkansen seat cushion and backrest cushion set. Can be used separately. Each corner has strings, so it can be fixed to a chair. The tags have been removed, but it's unused. It has been stored at home in a bag, so the backrest cushion has wrinkles on the back. Size: Backrest 【approx. 22 x 29 x 4 cm】 Seat cushion 【approx. 27.5 x 27.5 x 5 cm】
