The SIL-X Implosion 100mm is a transparent rotational molded shell, which is softer and more elastic than the standard SIL-X shells. This size ball is good for 3 balls jugging or contact juggling. Many contact juggler like this type of balls because the silicone inside the ball slows down the roll in/on your hands. It also is easier to balance the ball on your head or arms as the silicone goes to the bottom of the ball and makes it more stable.
