This stress reliever toy made of silicone. Ever catch your children, or maybe even yourself, popping the bubble wrap of the box of a package? Then you'll love this bubble for play. Just press the mouse bubbles down and they make a slight popping sound; then flip it over and start again! Endlessly reusable and washable, too. It has a simple game, players take turns pressing down any number of mice they wish in a single row. The player who presses down the last mouse loses. 5 3/4"L x 5 1/4"W x 5/8"H
