These decorative BeadAligners will stabilize any bead with a 4mm hole and eliminate wobbles. Large Hole Bead Reducers feature a Bali style and are designed to fit into Large Hole Beads, reducing the hole size to accommodate smaller stringing material. With these Beads you can reduce the hole size from 4mm down to 1.25mm. They also work great as a plug when using a Large Hole Bead as a pendant or focal point on a necklace.
