These masks are great. Arrived on time. I'm using them everytime.
Best fit of the masks I've tried. My first order was the 10 pack -- shipped UPS and arrived on time. Alas, my second order was shipped USPS and has been stuck in their Atlanta black hole for 5 days now. I suggest requesting shipment by UPS.
This is the best mask I have bought so far and I have bought a lot.
I highly recommend it.
For these days of heightened potential risk, a comfortable and secure fit in a pocket friendly folding design
