This is a silent wheel for small animals. I purchased it for a hedgehog and used it. I used tape on the center of the wheel to prevent claws from getting caught, so there are tape marks remaining. I washed it, but couldn't remove them completely, so I'm selling it as is. As a bonus, I'm including a reversible heater for winter. Please note that it doesn't have a box. 【Silent Design】 This wheel is designed to be quiet, so your pet can exercise peacefully. 【Large Size】 The large size of 31cm in diameter is suitable for various small animals, allowing them to exercise comfortably. 【High-Quality Material】 Made of durable plastic material for long-lasting use. - Brand: CASA - Product Name: Silent Wheel 31 - Color: Brown - Size: 31cm diameter - Material: Plastic
