Thank you for viewing. This is a size 7 airless basketball-style ball. The material is TPU (a soft, rubber-like material), so it doesn't bounce like a regular airless basketball. The sound of the bounce is also quiet, so I recommend using it indoors for handling practice or displaying it as an object. The ball surface has a raised shape similar to a real basketball. This was created by me using a 3D printer, so there are unique layer lines. Thank you for your consideration.
