I purchased this last month for 6660 yen, including the special garbage bags. I bought the child-sized type because my child was initially scared of the adult toilet during potty training. However, after using it a few times, they started using the adult toilet, so it became unnecessary. Therefore, it has only been used about 4 or 5 times and is in clean condition. Also, only about 2 of the special bags have been used, and about 98 remain. Although not as convenient as the special bags, I have confirmed that L-size garbage bags from 100-yen stores can also be used. It also uses AA batteries, and when you press the button, water flows. That part is unused and still new in its bag. Shipping costs a little extra, so I'm listing it for 4500 yen. Thank you.
