This is a mug molded from a North American Bison Horn. These are customized with other details, including skeleton hands, octopi, knuckle dusters, etc... FYI and contrary to the song “Home on the Range,” buffalo do not roam in the American West. Instead, they are indigenous to South Asia (water buffalo) and Africa (Cape buffalo), while bison are found in North America and parts of Europe. ... Bison sport thick beards. Buffalo are beardless.
