These vintage glass hearts were made in Czechoslovakia in molds during the 1980s. This heart is 10 mm from hole to hole and 9 mm wide at the widest point. The heart is frosted, so it is translucent. It also has a small etched detail each each side of the bead channel, where a clear line helps define the heart. The bead has a small hole and would be appropriate for 0.5 mm cord. Price is for 10 beads.
