lol humour me and read this before your instincts tell you to flame lol
so Im in dollarama, and I notice they started selling $3 items now, and one of those is these safety glasses.
I pick them up notice they say ansi and msa cert. On the glasses they are inscribed as well with ANSI Z87.1-2010.
I take them home, try them on, and yeah they feel great. They are very lightly tinted. I decide to shoot them up. Use .25 bbs from 2inches away and 5 feet away, about 20 shots, and what do you know? They held up flawlessly.
I decided while writing this to check on the msa safety works website, because these glasses do have a part number on the package, and sure enough here they are
