This Review Title is buttons are too small and the content is: While it's a good idea in theory, the buttons on this headband are too small to be functional.  They don't hold the masks in place.  I ended up just keeping the headbands and sewing on the bigger buttons  myself to make it work, which defies the whole point of buying these headbands in the first place..There are other information for this review, one is This reviewer did purchase it and the other is 0 people think this review is helpful.
