- Simple but effective relief for those who live with autism/stress. Hair pullers, skin pickers and other sensory seekers may find relief from their anxiety here! Pressing the mouse bubbles down yields a slight popping sound. Press them all, then flip it over and start again! Only a discrete pop sound is heard. Easily quiet enough for church or any other place where quiet is required. Only the user hears the soft pop of silicone. Perfect for children, adults, and our elderly! Made of silicone, they have a comfortable touch, are endlessly reusable, and dish-washer safe. Hone fine motor skills with games!
