Large Hole Beads (Greek Ceramic Beads, Coral): Ceramic bead in a loosely formed cornflake shape, Coral, ø 15mm. We use them as spacers and as bead caps. These ceramic beads in coral are exceptionally hard wearing due to the high temperature used when firing the coral color onto the ceramic base. In addition ceramic beads are very heavy and impossible to break. These are beads with up to 4mm large holes, very individually shaped--not for perfectionists.
