Review on 10-Pack Of Clear PET Sheets - 11" X 14" X 0.04" - Lightweight And Shatterproof Acrylic Panels For Affordable Glass Alternatives, Ideal For Poster Frames, Counter And Pet Barriers by Ryan Springer

Can you see it? No. So it's as good as glass to my eyes. Easy to cut with razor knife. ( make a few passes and not try to cut it in one pass) Also Try to just but the right size so you don't waste as much. I', ordering more for a couple more frames and to have some on hand. These frames were made from hardwood scraps glued together to make boards for the frames.
