My favorite solution to mask fog
I've tried several products to avoid being blinded while wearing a mask, and this is my favorite. It is so easy to throw one of these (or several) in my pocket, purse, and car and always be ready to treat my glasses or sunglasses. I think the price is very fair for what you get. They are one use only, so you are not stuck with putting away a spray or reusable cloth after use. Perfect for travel. These meet a very clear need!
