I've just started making plates/bowls with distinctive cuts and had some hard to reach areas that needed to be ground into profiles. Found this set of 7 for about the same price as two local stores. These aren't big balls, they're small ones, with a variety of shapes that suit me. They break and leave their dust, but they work quickly and will be bought again.
