These Czech glass beads are pressed for a uniform shape and size with a tapered design. The profile of the super duo is much like an inverted hourglass, tapering at the ends and Widening in the middle, and create a "honeycombed" or diamond pattern when stacked together. Their large hole size to bead size ratio makes them ideal for consistent bead weaving texture and multiple passes of fine beading thread, such as fire line, power pro, Koi thread and Nomo. Create beautiful textures with the multitude of colors available.
