Fixer beads are designed to fit around and hold cabochons or rivoli shaped crystals with the groove that runs along the inside of the bead. Vertical Fixer beads have 4 holes directly through the bead (2 above the groove, and 2 below the groove). With generously sized holes, Fixer beads are perfect for bead stitching patterns, stringing projects, and adding structure. Fixer beads come in bags of 20.
