Respirator Gas Face Mask NEW

Description

Not really sure what model this is as I don't speak Chinese. When I use my phone and hit google translate it says something to the effect of 40 mm dans gas mask. It is new in box. I had to squeeze it out to take pictures of it. Lot # Shelf. Maybe if you use your phone and scan the box with google pics, you can get more info sorry. It's 100% brand new and never been used or taken out of box until now.
