These masks do not properly fit your face. They come with grommets to tighten the straps, but try getting them on. There are no instructions on how to do this. I paid 13.99 each for our office staff, and I don't think we will be able to use them due to poor fit. Highly disappointed. The personalization was nice. I just wish they would have come with the grommets already on them to adjust for proper fit. Also, the filters are very difficult to get inside the mask.
