Review on Pack of 50PC Adult Butterfly Print Disposable Face Cover – JINF ATRISE, Fashionable and Reusable Mouth Cover for Women, Ideal for Cycling and Outdoor Dust Protection by Ricky Habbani

I wouldn't wear these if you want 'serious' protection, they are listed as non-medical and I have to agree (shame). I was able to wear one of these comfortably for 8 hours in the office and an 18 hour travel day with no issues. Depending on the mask, my ears usually screech after 4-6 hours and with these they didn't chirp even after an 18+ hour day. They are very cute and have received many compliments. I'm very glad I bought it and was tempted to buy another set just in case, although the one I have (50 masks) will probably last a while.
