Back in the 60's and 70's, the Beatles seemed to be the center of everyone's universe and the mood ring was wildly popular. It changed colors when you wore it...like magic! Today there is a modern-day equivalent, the “mirage” bead. Made of thermo-sensitive liquid crystal, it continually changes color based on the temperature around it. For Janice and other old hippies, it's just groovy! With a generous 3mm hole, you can feed two lengths of 1.52mm Indian leather through. Enjoy but please do not immerse in water.
