A great size for even pre-schoolers to grip! Our softest ball is best suited for Pre-K and elementary aged kids. Set of 5"-diameter balls, constructed with a low bounce, low density foam (25kg/m3), one in each of our Spectrum colors. Certified Latex-Free. As with all our Gator Skin balls! The tactile, non-sting coating makes them easy to grip, and the coating is so durable they're virtually tear-proof! No more red marks from the stinging hit of a vinyl-coated or rubber ball, so everyone can play at ease and build confidence, catch after catch! Non-sting coating is a proprietary polyurethane.
