Back in the 60’s The Beatles amazed 400 million people with their music and today that number has just grown. Just as they transformed the world of music and pop culture, these pink mood beads will do the same for your designs. As your body temperature changes, so do the thermo-sensitive crystals in the bead. Trippy! The core is silver-plated brass and with 2.5mm holes, the skies the limit in terms of design. Try it in Setting the Mood.
