Since we do not chemically treat our bamboo toothbrushes, it is important to keep them in a dry storage area and not sitting in stagnant water. The diatomite, biodegradable toothbrush holder is made of 60% diatomite (sand) & 40% clay, designed to be breathable, antibacterial, and quick drying for optimal storage of your bamboo toothbrush. Test it out, run some water over it and watch how it instantly dries.
