I ordered two of the meme masks. They came quickly, far more quickly than anticipated. However, they are exceptionally hard to breathe through. They are 88% polyester, and 12% latex. Basically, you're trying to breathe through plastic. I tried to leave a review on their site to warn others, but of course, it was removed. They seem to post only their positive reviews.
Please, purchase a COVID mask elsewhere, and make sure it's made of linen, rather than this subpar material.
