The ultimate dimpl experience! Built into the strong, high-quality plastic frame are 25 dimpl bubbles in four different sizes and a rainbow of colour just waiting to be pushed, poked, and popped again and again. The squishy silicone is fascinating for the fingers. Watching the board go from un-popped to popped is curiously satisfying. Young, old, - no matter who you are - your fingers just can't stop! Bubbles made of 100% food-grade silicone. BPA-Free, fully safety tested, hand washable. 2+ years.
