Makes all the difference in comfort
These simple straps are easy to snap on to the face mask, and the adjustment toggle makes it easy to pull to the desired tightness to keep the mask firmly against the face which is an added safety measure.  It is so much more comfortable than putting straps behind the ears.  It took me a while to find the best place to tighten it, but once I did, putting it on is quick and easy, and I like that it can hang from my neck when I don't need it.  I have lost several masks in the past, and this has solved that problem.  .  Furthermore, with so many in the bag, I have been able to share with family and friends, and they all find them comfortable and functional and so much better than fastening behind the ear. They are very well made, and I have had no breakage so far.  I will definitely reorder if and when it is necessary.
