One fatal flaw.
I put the mask on and opened and closed my mouth several times. The mask fell below my nose immediately. I pulled it up and tightened the ear loops. I opened and closed my mouth several times again. The same thing happened. There needs to be a nose pinch.<br /><br />I work in a grocery store. I talk to customers all the time all day. This product is useless to me. I am returning it.
