I used this at the beginning of toilet training. The seat part is removable and made of plastic, so I have washed it in the bathroom. The Anpanman part has been wiped clean. Operation has also been confirmed. I will ship it with the batteries included. I am also selling other children's items. ↓ #KZM_ChildrensClothesList An Anpanman-designed potty that lets you enjoy music and sound effects. - Character: Anpanman - Color: Yellow - Features: With music and sound effects buttons - Material: Plastic Thank you for looking.
