Review (3/5): As a headband it's nice, but...
I bought this because it had buttons to hold my face mask. I work in a school and need to wear a mask all day long, leaving my ears being sore from being bent by face mask straps all day long. I saw this and thought the buttons were the perfect solution. Unfortunately, the fabric is too soft and thin to support the tension of the mask pulling on the buttons. On one mask, a button fell off as soon as I hooked the mask on. One band was ever so slightly sturdier and was able to hold my mask semi-securely so I was able to wear it on a particularly painful day, but I wouldn't say it provided an adequate fit of the mask to my face. It was way too loose. So, it'll work in an ear pain emergency if you really have to have it but it won't work very well and it won't seal properly so your mask won't really serve it's purpose. If you're looking at this to hold your mask, you're probably better off looking at something else. I will say, however, that they come in 4 very pretty floral patterns that I'm sure I'll wear as just a regular headband at some point and they're very comfortable and stayed on my head well so it wasn't a total loss.
