This is an antique, Czech, Bohemian, molded, glass, interlocking, imitation, snake, vertebrae bead set which comes via the African trade. These glass interlocking beads were designed by Bohemian bead makers to mimic the real snake bone vertebrates which were worn on traditional necklaces by some African tribal members. This bead set is in great condition with some wear including slight dings and would be excellent for jewelry making or adding to your African trade bead collection. Average bead of the set measures approximately 6.15mm long by 9.09mm wide.
