Sponge, Sponge ball, pill
Sponge balls that don't roll away. These are called Sponge Ball Pills because they have the shape of a round pill or aspirin. They are flat on the top and bottom so they do not roll off the table as easily as ball shaped sponges.
These are a favorite of George Robinson's due to their size and shape. You can perform all the sponge ball moves with these with little to no change in the way you handle them.
Four to a set red super soft. Includes instructions by George Robinson.
