Soft color plays along the surface of these 4mm crystal ab druks, caused by a partial iridescent finish that catches the light. Try these beads with pastels or add them between jewel-toned beads for contrast. This pack contains 100 beads. Czech glass druks are round pressed-glass beads made in the Czech Republic. These beads are still made in small quantities by hand. Be sure to explore the rest of our Czech glass druk beads for other colors and sizes.
