Someone standing way too close to you at the store? You don't even have to say anything - let this mask do the talking for you!!! (Assuming said person knows how to read!?) These unisex reusable cloth face masks are made of 100% Polyester and provide a stylish physical barrier around the face. When used properly - can lower the risk of infection. They, however, are not medical-grade, thus, not meant for medical use. Great for everyday use.
