Antique Opal-Blue African Trade Beads
Antique football-shaped Czech glass beads, made in the 1940's and traded in West Africa. These are an unusual bright translucent opal-blue glass bead with some surface resin-y stuff which could be washed off I think.... Beads average 16mm x 12mm diameter. 39-40 beads in per strand, one broken bead.
