I have ordered these mask several times for myself and my family. However, the most recent package pertaining these mask I received had a very strong odd odor on them when you put them on. I'm not sure if it's something they used while making them or packaging them. It wasn't a gross foul odor just an unusual but intense odor due to it being close to my nose and mouth I had to open both packages of mask and leave them out. Doing so did release the odd smell this batch of masks had.
