The brackets are perfect to stitch inside masks for better breathing.

This gives a little room to breathe with the mask on. Just make sure the mask is large enough.

Overall, Great Product

Yes They’re terrific! They make wearing a mask so much more comfortable- you can speak without your mask getting into your mouth, and breathing is so much easier! The price is great, as well as the fast delivery and free shipping!
