Guard your toothbrush against particles in the air, dust, grime, and other contaminants with these Lewis N. Clark Antibacterial Silicone Toothbrush Covers - 4 Pack. When we travel, go to the gym, or go camping, our personal care items get dirtier than if they were just sitting in our bathrooms. They're exposed to the insides of our suitcases, hotel counters, recreation center bathrooms, and more. Instead of wondering if your toothbrush is still safe to use, you can protect it from the start. Made from food-grade silicone, these covers are free from chemicals like BPA and phthalates, and are built to withstand the heat from sterilization. They're easy to wash and can be reused many times.
