FIREFLY CHILDRENS TOOTHBRUSH is a fun-time timer toothbrush designed to encourage children to brush for the recommended 2 minutes which helps to form a healthy brushing habit while enjoying it. It flashes for 60 seconds and turns off automatically signaling children to stop brushing the top row of teeth and begin brushing the bottom row. The soft bristled 2 pack toothbrushes are equipped with a suction cup bottom. Batteries which are included last the life of the toothbrushes and cannot be replaced.
