Thank you for viewing. This is a set of a potty training seat and a step stool. The potty training seat has a detachable seat cushion and base, making it easy to clean and keep sanitary. The step stool has foldable legs, so it doesn't take up much space in the toilet. It has been cleaned and disinfected, but please understand that it is a used item. I will ship it via Kuroneko Yamato's Takkyubin (home delivery service).
