A limited run of bison leather featured in our volcanic series. Cinder tan bison is an embossed leather with a distinct, wrinkled appearance to give your projects a rugged look. At 3-4 ounces thick (around 1/16″ or so), this leather will work great for making bags, wallets, cases, and more. Holes and other imperfections are possible, especially with bison. Sides average 17-20 square feet.
