Yuck-E-Balls are among the most tactile, oversized balls to hold and their weight provides great kinesthetic feedback. Yuk-E-Balls' seamless PVC shells are durable and filled with 3/4"D (2cm) PVC balls in a non-toxic gel. This combination of materials creates a fluid environment, within which the PVC balls glide easily when squeezed. Yuk-E-Balls stop where dropped, making them a great alternative to beanbags.

Balls are perfect for squishing, squeezing and tossing. The student who fidgets will find calm, stress relief and hand strength in squeezing the Yuck-E-Ball.
