This is a metal silent exercise wheel. - Wheel diameter: Approximately 320mm - Wheel width: Approximately 120mm - Size: 350mm (W) x 170mm (D) x 370mm (H) It has been cleaned at home and stored. The bearings are in good condition and the wheel rotates quietly. The wheel itself is relatively clean, but there is some paint peeling and rust on the four corners of the base that touches the floor (see photos 3-6). The outer box and other accessories are not included; the item will be provided as shown in the photos. I used this for about 5 years to raise a hedgehog. Please be aware that this is a used item, so if you are concerned about the condition, please take that into consideration. Thank you for your understanding. Thank you! #exercise wheel #hedgehog #degu
