These arrived quickly and have a very cute design!I get on average 2-3 people at work (hospital work) ask what sort of mask this is and where I got it. It's easy to see it seals because when you talk, air can be seen moving under the mask (that's a good thing). Although not a medical mask, I feel like it helps for general purpose- it is NOT an N95 and not safe in isolation, but a nice mask for protection around people you don't know!NaI love these masks and they are so cute. I work in Healthcare and get compliments on them all the time!If you have a normal face size they do run true to size of a surgical mask they are about the thickness of a surgical mask the colors are nice and the fit is nicer than a rectangle surgical mask but I feel they offer as much protection as a regular surgical mask. They are comfortable and even after eight hours straight wearing them for days they don’t make the back of your ears soreI really like these masks they are pretty and don't hurt my ears with the straps.They fit great but they are to hot for the summer. I couldn’t breath very well. I’m not saying do t buy them, like I said they fit well, just because I don’t like them doesn’t mean you won’t.These facemasks are super comfortable and fit well. I have been wearing them everyday for the past week. I immediately noticed they had a strong chemical smell, but I personally feel that all disposable masks have a chemical or unpleasant smell. My issue is the chemicals are causing my eyes to burn. This issue has been getting worse as time is going on, and I'm now at the point where I can no longer tolerate it. I am reaching out to the seller to see what my refund options are now.
