Large Hole Beads (Greek Ceramic Beads, glazed Seafoam): Ceramic bead flat triangles or washers, glazed Seafoam, ø 12mm. We use them as spacers or end beads before the bead tips. These ceramic beads in glazed Seafoam are exceptionally hard wearing due to the high temperature used when firing the glazed Seafoam color onto the ceramic base. In addition ceramic beads are very heavy and impossible to break. These are beads with 15mm large holes, very individually shaped--not for perfectionists.
