Large Hole Beads (Greek Ceramic Beads, Aegean Mix): Ceramic bead in a loosely formed cornflake shape, Aegean Mix, ø 20mm. We use them as spacers and as bead caps. These ceramic beads, Aegean Mixare exceptionally hard wearing due to the high temperature used when firing the Aegean Mix onto the ceramic base. These are beads with 4mm large holes, very individually shaped--not for perfectionists.
