Thank you for viewing. I am selling this because my cat has not used it at all, even though I purchased it in November 2025. ( ；∀；) I purchased this item from "ff-koubou" on Creema. The weight capacity is expected to be around 15kg, but I think it would be best for small to medium-sized cats. ◾️Product Site https://www.creema.jp/item/18344068/detail ※The size from the floor to the ceiling in my room is 240cm. ※There is some color transfer on the parts of the supports that were in contact with the steps. Also, there are marks on the steps from tightening the supports. ※I will also include the installation instructions. ※Since this will be picked up from my home, it is likely that it will be shipped on weekends after January 10th (Saturday). Please understand. ※The photos show the scratches that I could confirm. (The black oval steps have areas where the color hasn't fully set.) In addition, there are other minor scratches (less noticeable than the red and yellow steps). If you are concerned about this, please refrain from purchasing.
