Hand carved Bird Fetish set of 3 with3 materials to Choose from Bone ....... Diagonal (Back through belly) Black Buffalo Horn ..... *New drill style*. (Back through to chest). This offers additional mounting styles and the creative freedom to have the bird fetishes in motion. Shell ...... *New drill style*. (Back through to chest). This offers additional mounting styles and the creative freedom to have the bird fetishes in motion. Like all things in nature, no two are alike. Drilled Diagonally, (bone) Angled, (Shell and Black buffalo) for use in Earrings, Necklaces and Bracelets. Also commonly used as fetishes on Regalia.
