Button will fall off and you'll only have a bandanna to wear... in about a day
I use a face mask daily for 8-10 hours.. great comfort was very happy.. BUT, then 4 hours in the button fell off.  Not what I was expecting.. came home and realized I have to reinforce them ALL.... if i want them to serve its purpose.. poor quality in the button stitching... have a needle and thread at hand....  will be looking for a different maker to buy...
