These sweet black glass beads are just what you need for an accent. They are 5 mm thick and 8 mm wide. The widest point has a bit of texture, almost like a traditional squash blossom bead, but the texture is only around the middle. The top and bottom are flat. The bead channel will accommodate up to a 0.5 mm cord. These are vintage Czechoslovakian glass beads made in molds during the 1980s or early '90s. There are no visible mold marks. The bead is shiny, black, and opaque. Price is for 10 beads.
