Our potty training patches contain a glue, waterproof coating. It can validate every experience of your little one, as his/her "pee magic" displays his/her favorite animal in the toilet training toilet, inspiring kids to use the toilet again and again. The way to use it is simple: place the sticker on the inside or side of the bedpan so that small children can easily see it. And can train children to go to the bathroom good habits.
