100% cotton fabric face masks.  These are in NO WAY medical grade or have any sort of filter in them. These are a basic fabric mask designed to simply wear as protective coveirngs while you go out and to be washable.  Made with the recommendd CDC pattern except that the elastic is not completely sewn to the fabric, so it's still completely adjustable. Please note - the elastic on some items might be a little thick, some of the materials are getting to be a little difficult to find. I found that pulling my ears out to adjust for the thicker elastic made them slide snugly into a comfortable position.Please note!! If you're elastic is too short it is brand new!! Try stretching it out a bit first. If it's still too short message me and I'll see what I can do about sending over more.
