I am in the middle of a hollow vase type form, with some punky areas, and I need something better to help me sand the inside. I have a vague memory that somewhere I saw some apparatus that is basically some type of a ball on a stick that has hook and loop strips that fit over the ball

Does anyone know of such an animal? I hope I am describing the thing in a way that makes sense, but perhaps some of you are a bit more aware of what is out there.........I have not seen it in my visits to CSUSA, or other places.........maybe someone can point me in the right direction. Thanks in advance!
