Made in Czechoslovakia during the 1980s or early 90s, these beads were made in molds and then acid washed for a matte finish. The incised pattern is sharp and quite modern. The pattern is on both sides of the bead, so it will always show. The bead is 18 mm from hole to hole and 12 mm across. The bead is 6 mm thick. The bead channel will accommodate a 0.5 mm cord. Each strand has about 25 beads.
