I bought it on Amazon for around 8000 yen and used it once to test it out, but my cat didn't like it, so I'm putting it up for sale. I'd rather give it away at a bargain price than throw it away. I washed the tank only, and haven't cleaned the rest, so please be aware that there may be some cat hair. Aside from that, it's practically unused, so I think it's in good condition.
