Sensory Pop Ball PDQ

This 6cm hexagon-shaped ball is filled with air and its surface is covered with3D  bubbles that can be pressed in before the ball is squeezed forcing all of the bumps to pop back out with a satisfying noise. 

Great fun as a sensory or fidget toy, the challenge is to see how many bumps can be pressed down before they start popping back.

The balls come in an assortment of colors and is supplied in a PDQ display box.
