This 3 ply disposable protective mask is made of a water-blocking non-woven fabric outer layer, a meltblown fabric protective layer and a new non-woven fabric inner layer. One side of the mask contains iron core and nose bridge core, which can be deformed at will, so that it has a tighter protection. The ear hooks have good elasticity and are very comfortable to wear. Use it to protect the wearer from inhaling harmful particles, odorous gases and bacteria. 6 22/25"L x 3 3/4"W.
