Czech Glass Superduos are a popular choice for beading enthusiasts due to their unique shape and two-hole design. These beads measure 5.5mm in length, 2.5mm in width, and 3.5mm in thickness, with two 0.8mm holes for stringing. They are conveniently packaged in hangable plastic tubes, each containing approximately 22.5 grams or 340 beads. The Turquoise Green Picasso variant offers a vibrant and artistic touch to any beading project, reflecting the rich tradition of Czech glassmaking.
