Nyan-tomo Clean Toilet Main Unit

Currently negotiating.

Thank you for looking.

This is the Nyantomo Clean Toilet main unit, Amazon limited edition light gray. The box in the 4th photo has been discarded, so I will put it in a newly arranged box.
I purchased it about 2 years ago and my cat used it properly. However, I tried introducing a clumping litter toilet, and my cat stopped using this one entirely, so I am selling it.
Although it was used, there is almost no sign of wear. I have washed it and air-dried it in the sun, but there might be a slight odor of urine.

I will also include some leftover small-sized Nyantomo litter (not enough for one full use...) and 5 sheets.

Please check the condition and purchase only if you understand this.
