Leather pros Parabellum are known for their impeccable craftsmanship, made apparent through all of their products, such as this bison ID case. The majority of Parabellum’s goods are made using leather from US indigenous Reservation Bison, with the whole leather process (tanning, cutting, stitching, etc.) done by hand. This slim ID case is a good alternative to the somewhat bulky wallet, and is especially useful when traveling. Available at select retailers.
