Thank you for viewing. I bought these for a rabbit before, but they were too small to use. They are unopened and unused, but they have been stored at home, so please purchase them if you understand this. ① Chewing Wood Ladder Material: Body: Natural wood, Screw: Steel, Washer: Steel Dimensions (Width W x Depth D x Height H) (mm) 75 x 30 x 197 (including fixing parts) ② Chewing Wood Cone M Material: Body: Poplar wood, Screw: Steel, Washer: Steel Dimensions: Diameter x Height (mm) 40 x 130 (including fixing parts)
