"Ack! All of my beads fall off as soon as I get my necklace made!" Have you ever said or thought this, if so then you need the bead stopper! It clamps to the end of you thread/wire and allows you to add and subtract beads without the worry of beads falling off. This tool is ideal for any size bead. Sold individually, buy 2 in order to have a stopper on both sides of your necklace!
