Vintage small green two-hole square beads

This is a most unusual green. A cross between forest and moss, perhaps? Made in Czechoslovakia probably during the 1950s in molds. The hanks of beads still had their original tags on them when I got them and they are from the era when the tag said “Made is Czecko-Slovakia” These neat square beads have two holes. This would make them perfect for a bracelet, fun earrings, or most likely their original intention, to sew on clothes. The square is 10 mm wide and 5 mm high. The face of the bead is faceted and the middle comes to a flat circle. The back of the bead is open. Price is for 10 beads.
