Black + Gray Modern Tribal 1-1/2" or 2" "Ocho"
Large, thick, flat disk, smooth black button hand-carved from horn. Lines and slashes are gray. Dynamic, strong button that may make a wonderful pendant, too. Shape, size, thickness and color are very consistent button to button; the slashes vary a bit since they're done by hand one at a time. Lighter in weight than it looks. We call it Ocho.
Both sizes are 3/16" thick.
