Review on Advanced Disposable Earloop Outdoor Filter Masks for Enhanced Occupational Health & Safety by Daniel Shankle

Unfortunately I had to return the masks that arrived because of the strong smell that gave me a headache and nausea. They were thinner than I expected which might explain the great price! They were packed in boxes of 50 in sealed strong clear plastic bags. If you buy 2000, you need a lot of memory! The box I received was manufactured in May 2020 and expires in May 2022.
