This is the protective case that provides a more convenient and sanitary way to store a fabric or disposable face mask. A far more hygienic option to hanging a mask from a car's rearview mirror or stuffing it in a pocket, the hard shell plastic case is infused with nano silver ions that inhibit the growth of bacteria. In independent laboratory tests, the case reduced bacteria from its surface by 99% over a 24 hour period. It tucks easily into a purse or glove box, providing effective protection whenever you're away from home. Its antibacterial properties won’t diminish over time and it can be disinfected with alcohol. For use with any washable fabric or disposable face masks. White. 3/4" H x 5 1/2" W x 5 1/2" D. (3 oz.)
