These are the best hand made face masks I had tried so far! They are face contoured and double layered and have an opening to insert additional protective layering. And they are a wonderful fit. I ordered 2 sets. And I just ordered more for family members!
Ties that go behind the head keep a mask on much better than do ear loops. When I need a mask to stay on tightly for long periods, I wear these masks. They are also of heavy material that will help keep viruses out!
