Combi Western-style potty I think there are no noticeable stains. I used it by cutting and laying an overnight sheet or cutting the side of a disposable diaper inside. The step stool is attached to the back. I used it for toilet training, of course, and also when I was worried about children's toilets, such as when camping. I thought it could be used in a disaster, so I kept it, but my child has grown and can now use the same toilet as adults. I will put this box in a plastic bag and ship it as is. Thank you for your understanding.
