Sold by the strand. 6x9mm with a quantity of 25 beads per strand. 3mm hole (drilled) so great for leather cord or other types of cord. These beads are so beautiful, and were painstakingly made by hand. First the glass bead is made, then faceted by hand, then coated with metallic gold, then etched, and finally drilled to be a large hole bead. This is why they are more expensive than most Czech glass beads.
