Anti-fog cleaning dry cloth for eyeglasses. Simply blow and wipe with the cloth, which will dissolve the anti-fog coating on to your lenses and easily prevent them from getting fogged up again. No need to worry about fogged glasses when enjoying a meal or when wearing a mask. This re-usable dry sheet can be used for approximately one month. One the cloth has lost its anti-fog properties, you can still continue to use it as a regular cleaning cloth for your eyeglasses. Glasses Cloth 9.5x16.8x0.3cm
