High-resilience urethane donut cushion (Retail price: 3280 yen). Thank you for viewing. I purchased this in preparation for childbirth, but I had a C-section and didn't use it, so it has been stored at home. I couldn't find any stains, but please refrain from purchasing if you are concerned, as it has been stored by a private individual. Home cleaned. - Color: Brown - Weight: 400g - Material: High-resilience urethane - Width of the donut hole: Approximately 18cm - Cover: Washable
