All of our horn beads are water buffalo horn (unless otherwise stated). Naturally, the horn is a black color, but can be bleached and dyed a variety of colors, from bone white, to amber, brown and deep red. These beads can be crafted to have a smooth, shiny finish, or they can have a variety of designs etched into them. The holes on these beads are large enough to fit Leather Cording, Organic Cotton Cording, Su-Preme Cord, and Hippie Hemp.
