The Toothbrush Sanitizer Case with UV Light eliminates 99.9% of disease-causing bacteria from your toothbrush. It is simple, easy to use, and hygienic. Instead of a wet, germ-infested brush head entering your mouth first thing every morning, you can use a clean toothbrush every time. The portable toothbrush sanitizer is powered with 2 AAA batteries not included. The UV light automatically turns off after a few minutes of use. The size of the product is 21.8 (L) x 5.3 (W) x 2.8 (H) cm.
