The Firefly Spider-Man Ready Go Light-up Toothbrush features lights similar to a traffic light to teach kids how long to brush. When ready to start brushing, this toothbrush flashes green to go then yellow that time is almost up and red that it's time to stop brushing. This fun light technology keeps kids entertained while teaching healthy oral care habits! The Firefly Spider-Man Ready Go Light-up Toothbrush features soft, rounded, premium DuPont Tynex bristles and a powerful no-mess suction cup so it easily stands on your bathroom countertop.
