Metal Pottery Hand Wheel Diameter: 22cm Height: 5.5cm This 22cm wheel is easy to use, even for beginners. It has no rust and rotates very smoothly. My mother used it a few times and then stored it in a warehouse. The box is damaged, but I believe the wheel itself is in good condition. Please check the images. Please understand that this is a used item before purchasing. *I do not have any knowledge of pottery, so I cannot answer specialized questions.
