Review (5/5): It works
It’s a necessary comfort you must do for yourself if wearing a mask. The piece fits against the mask and your face easily and comfortably. Quick to clean and dry, not that you’ll need to rush because you get 10 or more. I teach fitness classes and it keeps the mask away from your mouth and nose with labored breathing. This is the reason I purchased was for speaking and projecting clearly while teaching.
It works like it should!!!!
