These masks are not the scratchy stiff blue ones or the cheap black ones.  They are made in USA and are the most comfortable masks for my family and for anyone who has worn them, they always ask for more.  You can re-use them several times, I did all the time. They fit better by wrapping under your chin. I have a large supply and are only sold by the box, with 40 per box and individually sealed. See more description in the photos.  I will combine shipping for up to 3 boxes of masks.  I have 100% Positive feedback, so buy with confidence!
