These affordable, lightweight face covers, literally, keep me breathing through COVID-19! I have fainted in public, prior to Coronavirus. So I don't like keeping two breathing holes - nose and mouth - covered! It's hard for me to breathe through my many face covers. But these 4 covers, are refreshingly different! They have inconspicuous, press-your-nose-through, little, holes! So I press my nose right on through, when I feel the need to breathe (smile). Clever invention!See full review
