Much more than a foam ball, The Gripp® was the first and it's still the best squeeze ball in the business. Every squeeze is different, so it's irresistible. Holds eight US patents. An innovative light-weight filler gives the Gripp® II a smooth fluid squeeze you have to try to believe. Just like The Original Gripp, it's non-toxic and unconditionally guaranteed. Optional juggling set packaging available. 2 1/4" Diameter
