Our battery operated dice roller is adapted with a 1/8" (3.5mm) jack to accept any standard switch, not included, that allows people with disabilities to "roll" the dice. Press your switch and watch the dice shake and roll! Now switch users can play games or have fun learning math skills with the dice. Comes with 5 dice. Clear plastic dome removes so you can add or change the dice. Black cover protects the dome when not in use and also allows you to play dice games that require the dice to be covered. Uses 2 x AAA batteries (not included). Small parts warning! This product contains small parts that could be a choking hazard. Recommended for ages 14+.
