Quick-drying waterproof box sheet, white Size: 240 x 200 x 40 cm Surface: 100% polyester Back: Polyurethane Original price: ¥5,580 Purchased in May 2025 from "Neko to Ohirune Waterproof Sheets and Sleep" on Rakuten Ichiba, but I am selling it because I purchased the wrong size. It has been opened and laid out once, so it is not unused, but it has been home-cleaned. It is for a family of 4, and is the size of a double and a single bed put together.
