【Silent Wheel Flat 25】 This is a small animal wheel that uses large-diameter bearings for stable rotation and reduces friction noise during rotation. Because the rotating parts are concentrated on the back of the main body, the surface of the main body is flat and does not hit the animal's back during exercise. Also, the wheel body can be attached and detached simply by twisting the bearing cover, making it easy to clean! Wheel diameter: 250mm Wheel width (depth): 110mm Target animals: degus, chipmunks, hedgehogs, etc. I bought it new and used it for a short period of time. There is some slight wear and tear, but I don't think it's noticeable. Of course, there are no problems. I washed and stored it after use. I have disinfected it for sale. The original box is not available, so it will be packed in a different box. Please understand. *Image ③ is for reference.
