Very thin masks and inside their packaging there are little particles that look like sawdust to me

It is not suitable for average and large faces. In the first mask I took out of the box, one elastic came off. The elastics are small. They put a lot of pressure on the ears and nose. It is only suitable for small faces. I regretted the purchase

Great mask, adequately covers the nose and mouth. However, it doesn't seem to be of good quality. It is quite thin compared to other N95 masks. Unfortunately, I was not satisfied at all...
