Large Hole Beads (Greek Ceramic Beads, Aegean Sky): Ceramic bead rondelles or very short tubes, Aegean Sky, 6mm x 4mm. We use them as spacers or end beads before the bead tips. These ceramic beads, Aegean Skyare exceptionally hard wearing due to the high temperature used when firing the Aegean Sky onto the ceramic base. These are beads with 4mm large holes, very individually shaped--not for perfectionists.
