This is a reusable hand-loomed cotton mask for children. This mask has two layers of 100% cotton fabric that has been polyester blended for extra protection. There is even a filter pocket between the two layers where you can place a tissue or paper towel for a third wave of protection. There is a wire across the top that forms the user's nose and face and there is elastic around the ears that hold the mask in place to give the a snug fit. Some of the nicest masks on the market today.
