Violight VIO200 Travel Toothbrush Sanitizer. No matter how often you scrub and clean, microscopic critters will still thrive in the warm, moist environment of the average bathroom. In fact, a single toothbrush can harbor millions of microorganisms -- millions! -- which means it's a good idea to sanitize something that you put in your mouth several times a day if you want to reduce your chances of bacterial infection. Easy, one-button activation with auto shut off in just seven minutes. Kills 99.9-percent of the bacteria living on your toothbrush with germicidal UV light. Small, compact size doubles as a toothbrush travel holder. Measures 8.5 x 2.1 x 1.1 inches. Travel sanitizer holds a single toothbrush (toothbrush included) and is operated by two AA batteries (not included).
