3+. Light & sound. Try me! 1 Minute Timer: Lightup fun. + sound effects. At Firefly, we believe in making healthy habits fun. Firefly's Light and Sound Toothbrush brushes away plaque, lighting up and talking to encourage longer brushing. As the light flashes, brush the upper teeth and then repeat for the lower teeth. Batteries included. When light no longer flashes, it is time to change your brush (approx. three months). Dentists recommend brushing for 2 minutes twice per day for proper oral care. www.fireflytoothbrush.com. starwars.com. Questions? Comments? 1-866-373-7374; comments(at)ranir.com. Made in China.
