Fit: Soft, secure and adjustable elastic loops fasten around base of head for comfortable and snug fit. Not only does it tighten the grip but when you're tired of using the masks you just remove the bands over the ears and they hang off your neck until you're ready to put them back on. Great for going out to restaurants, running errands and any place else that will require wearing a mask for a limited amount of time. Made in USA & comes in individualized packaging.
