Vibrant assorted color mix, Czech opaque glass tube / bugle beads. These thick tubular beads are glass reproductions of traditional shell wampum beads. Average size: 4 mm wide x 9.5 - 10 mm long. Approximately 2.5 beads per inch. Each package contains 10 grams of beads (shown in photos - approximately 42 beads). .:.All the beads I carry are colorfast. With the exception of beads with luster, pearlized, metallic, AB, or sol gel coatings, the color is in the glass itself, not applied to the surface. Many of these colors are no longer manufactured, either because they were too expensive to produce, the results of the recipe were too varied, or because the secrets of their manufacture were lost when the factories which made them shut down. These are tiny pieces of history, made with care & skill.:. Color Mix Wampum Assortment 4 X 10mm Czech Opaque Glass Tube Bugle Trade Beads Grams
