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. Fixer beads come in both Horizontal and Vertical hole configurations. Horizontal Fixer beads have 2 holes parallel to the groove, one on each side of the groove. 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.
