Large Hole Beads (Greek Ceramic Beads, Aqua Metall): Ceramic bead rondelles or very short tubes, Aqua Metall, 4mm x 2mm. We use them as spacers or end beads before the bead tips. These ceramic beads, Aqua Metall are exceptionally hard wearing due to the high temperature used when firing the Aqua Metall onto the ceramic base. These beads are very individually shaped--not for perfectionists.
