I feel safer wearing these mask it’s comfortable even around the ears.

Due to problems with international shipping -- fewer flights taking cargo -- it did take a few weeks for the masks to arrive, but they did and they're fine. And when I had trouble figuring out the tracking --- every time I emailed the company asking about status, they responded within a few hours. I was very impressed with their responsiveness. It eased my apprehension that they didn't provide a phone number. If only other companies were half as responsive.
I find the masks to be a bit too loose and so tightened the earl loops with a small knot b/c I was too lazy to sew in a stitch. Another trick I saw online  to tighten masks, is to use a bobby pin to attach the earloops to your hair.

Can these be uv steriled?

Masks are what was expected at a fair price

The masks are just what I needed, comfortable to wear.
