The latest evolution of the MMX.. This soft durable ball is the ultimate bean bag/stage ball hybrid. Although it appears to look much like the other MMX balls, this stage ball is very slightly under-filled giving it a wonderful squeeze and a little flexibility in the skin. This all adds up to a very tough stage ball that acts like a standard thud; it won't roll away when you drop it and the surface can be cleaned with a wet sponge. Its softness makes it ideal for endurance juggling and stalls. Highly recommended for jugglers of all abilities.
