I'm selling this because I haven't used it much. It's very clean as it hasn't even been a year since I bought it. Purchased on Amazon (photo 9) Bought for 9798 yen (photo 10) The scratching post part is also unused and clean. (In photo 10, the bottom step of the official photo has been discarded as it was not used) I'm still looking for the instruction manual. Assembly can be done with a hex wrench. I can ship the hex wrench together. Thank you.
