I purchased this item in May for 13,800 yen and am still using it. I am selling it because I no longer need it. There are signs of use, such as where a cat tried to climb it and where masking tape was used, but they are not very noticeable. The ninth photo shows the current condition. All the parts are shown in the ninth photo. I hope someone who understands that this is a used item will consider purchasing it. Regarding assembly, there is no box or instruction manual. I will disassemble it for shipping. I am also open to price negotiations, so please feel free to comment.
