The Steripod Clip-On Toothbrush Protector is designed to keep your toothbrush clean and fresh. It fits most manual and electric toothbrushes and helps prevent cross-contamination between brushes. The protector is infused with thymol vapors, a safe ingredient found in many mouthwashes, which helps keep toothbrushes smelling clean and fresh for up to 3 months. The simple clip-on design makes it perfect for travel, and it is made of durable, food-safe plastic without BPA.
