Silver, 4mm Miracle beads strung on a 7.5 inch strand containing 50 beads. Aptly named because of the optical illusion created by the glowing bead that appears to be a bead within a bead. They are made with a glass reinforced plastic and have layers of protective reflective coatings with a clear finish giving them their magical luminous look. They are lightweight, durable, brightly colored and have a good hole size in comparison to bead size, fitting a 1mm cord.
