Keeping your beads secure has never been so easy! The innovative Bead Stopper™ hold your beads in place and prevent accidental spills. Squeeze the ends to open, allowing you to slip wire, thread, or string into the stopper. To close, relax the squeeze. It's as simple as that! No need for alligator clips or tape, plus the Bead Stopper will not crimp your stringing material.
