Proofgrade Natural Leather is one of the highest quality leather materials available. It is beautiful by itself, but after months of use, it ages to a stunning, burnished glow. Because it is tanned with a toxin-free vegetable process, it takes oil, dye, and paint brilliantly to take on a limitless variety of appearances. It's also perfect for techniques like wet forming and embossing. Proofgrade Leather is perfect for quick gifts that look like they came from the boutique like bookmarks, bracelets, and wallets. Dive deeper to create purses, shoulder bags, and even footwear. Proofgrade leather is unfinished and masked on one side with a removable protective paper sheet for perfect prints; the barcode takes care of settings automatically.Details:Natural5" x 10" overall sizeMedium: 3/64" thicknessLeatherFor use with Glowforge 3D laser printer and for any CO2 laser cutter / laser engraver (sold separately)
