Easily hold beads in place using SmartBeads with BPS - an innovative Bead Positioning System that eliminates the need for crimps or knots! Each bead contains a rubber gasket inside its hole. The hole in this inner rubber lining is only about 0.3mm, but it expands to hold the bead in place on a variety of wire and cord. Best yet, Smart Beads can be re-positioned over and over again. Change your design daily by simply sliding the beads into a new position! Similarly easy to use are bead locks, which are perfect for add-a-bead and Pandora-style jewelry designs.
