The TinyMouse™ is about half the size of a standard computer mouse and just right for your child's small hands. A scroll wheel and colored right and left buttons help kids learn to click and move the cursor using the tiny mouse with greater comfort and control. And with optical tracking, there is no trackball to become dirty or lost, or to malfunction.
