***SOLD OUT***Introducing ZenKraft's American Bison Bi-Fold Notebook. This notebook is constructed from 6oz. Bison leather, has a stiff temper, but retains flexibility. It is a pullup leather that changes color hue when handled, producing overtime a beautiful patina! The Bi-Fold holds 6 regular size inserts comfortably without the dreaded overhang. Two Tech pockets allow for carrying small tech items like cell phones. I added a brass chain bookmark on this one, just because it seems suited for the piece. Folks its a limited edition and won't be around long, the American Bison Bi-Fold, by ZenKraft, enjoy!
