This prevents the mask from falling once it is removed from your ears. The prevents the mask from being placed on different surfaces and allows the holder to not loose the mask more easily.

I bought these for our trip to Canada. Not only are they as comfortable and anti-fog as advertised, they are very unique. Several people on our flight inquired about them; you may be getting some new business!

It’s the best designed mask system I have used. Well done. Z

I got it for my girls who wear masks to school cause they an myself catch everything so I got these for them we love them so far and they don’t forget them anywhere so these work perfectly to keep them from getting lost or left behind I wish y’all made a hook for the legs of the glasses to hook the ear straps on so it’s easier for kids

Love that I can have my mask around my neck when not in use. A little tough for me when trying to secure the ball into the hole but I have weaker hands. I think most people wouldn't have an issue with it.
