This is a Handmade Facemask made with three Layers of Fabric. It contains two outer layers of cotton Fabric & one inner layer of interface fabric which acts as a filter to help protect against dust & germs. Also, is a picture of the interface fabric that I put inside the mask. I’ve done an aerosol test on them & the aerosol does not pass through the mask! This Face Mask also contains a small wire at the nose area so you can secure to desired fit & with tie straps. PLEASE NOTE: I AM NOT MAKING CLAIMS that These will not prevent you from getting sick but they can help you & your family to not touch your face/mouth. Machine washable.
