**Update** The review below was my first impression. I requested and received a refund without having to return the product. The masks lay open for some time in the zip bag they came in. When I returned to them (I don't remember, a few hours or a few days) they were aired out. I've used them and they fit great and hold up well. I have changed my rating to 4 stars and will most likely order again. **Original Review** The mask itself is similar to other disposable masks with stretch and shape. However, the mask smells very strong when you take it out of the packaging. For most of the day, a person does not want to wear anything with an unpleasant odor in their nose. I got my money back from Revain.
