This is a hand-operated potter's wheel for pottery. It has a diameter of 19 cm (1 unit). It was new, unused, and boxed, but I opened it to check for the listing. The cardboard box has some dirt and wrinkles, but the wheel itself is in excellent condition. If you enjoy pottery or are thinking of starting, please consider purchasing. It's made of heavy metal. I will wrap the box in bubble wrap for shipping. I am also selling another new, unused potter's wheel of the same type, but without a box. If you would like two, please let me know in the comments section, and I will offer a small discount.
