Scraps of black cowhide leather. The first photo shows the entire amount. 570 grams. The white paper underneath is A4 size. There are some scratches and wrinkles, but it's relatively clean leather. Thickness is 3.5mm. It's thick and sturdy leather. Stamping is possible. It's a matte black, but I think it's the type of leather that will develop a sheen with use. The cut edges are not core-dyed, so they are natural color.
