This is a rubbery bubble popper that you can use as both a round counter and also use to as stress relief just popping the bubbles! The counter goes up to 100 and then you can undo the bubbles to keep counting. 

This is also just great as a stress reliever. 
 
The dimensions are 17cm x 17cm squared. 

It's made of rubber so if you spill on it, you can wipe it clean.
