This was included when I purchased a baby futon, but I never used it. I thought I might use it when my child was potty-trained, but I ended up buying a large bedwetting sheet, so I'm selling this one. It might be useful for travel or long trips, like when you get stuck in traffic. You could put it in a child seat or junior seat, and if your child has an accident, you won't have to wash the cover. ☺ It's a waterproof polyester bedwetting sheet, size 60x90cm. There are no smokers or pets in the house. Please note the following: * There may be storage wrinkles and fold marks. * The actual color may differ from the photos. * I may have overlooked something as I am a private seller. * I may change the shipping method from Rakuraku Mercari to Yu-Yu Mercari, or vice versa. Please consider purchasing this item, understanding that it is a used item, stored at home, and has been inspected by a private seller. Thank you for looking.
