5 Pieces Polycarbonate Sheets Clear Plastic Sheet Thin Rigid Plastic Sheet Clear Polycarbonate Sheet Shatter Resistant Plastic Sheets for DIY Crafts Document Picture Frames (12 x 12 x 0.02 Inches)

This product may be good for craft projects, I bought these for something else in mind. I ended up returning them

I couldnt find a decent aftermarket lens for my Miller Classic welding helmet and the OEM is just to ridiculously expensive. While the OEM lens is thicker at 1mm, the inner lens is mostly just a dirt shield for the auto-darkening lens and is not a safety feature (thats my opinion). And because the material is so thin, it easily cuts on my paper cutter. You could just as easy use a pair of scissors too. And for $12, Ill probably never have to buy another inner lens. Sheets come with protective plastic on BOTH sides. One side is green and its obvious, but the other side is clear, so remember to peel that side off too!
