Gymnic Giant Body Ball sized 33-1/2 inches in diameter, is strong, light and easy to grasp. The bounce and softness of the ball can be easily controlled by the amount of air blown in through the straw/inflator. Ball even bounces when semi-inflated, which is a desirable state that allows easy grasping by those with neuromuscular problems. Provides super touchy feeling, and floats just a little bit, providing a slower movement that's easier to eye track. This ball is tough, much more pliable than vinyl therapy balls and can conveniently support up to 300 lbs. Sold individually and ships in a random high-visibility color.
