SuperDuo Two-Hole Czech Glass Seed Beads
Super Duo Beads are a Czech made, glass Two Hole Seed bead.
Similar in shape to the Twin bead, but with a few very important differences.
Super Duos are a pressed glass bead with guaranteed size and dimensional stability.
They measure 2.5x5mm, with two .8mm holes.
They are not simply "coated crystal" but actual coloured glass with many coating options
