More info: No returns. Design printed on a single layer of lightweight antimicrobial treated polyester/spandex. 16" long, can be folded over if you want 2 layers. These are not medical masks. This mask is a super stylish simple barrier to help contain exhalations, sneezes, and coughs for when you can't hold back high-speed bodily excretions. A mask may help lower the risk of infection and combining that with social distancing is even better.
