Oxlasers Laser Safety Glasses Laser Goggle for 635nm 650nm 660nm Red Lasers and 445nm 450nm Blue Laser

They're about the quality you'd expect at this price. Not too comfortable. They arrived scratched and a bid smudged, and I wasn't able to clean any of the smudges off. Whether this is due to poor production or poor packaging during shipment, I'm not sure.

I received a scratched up pair of glasses.
