Cobalt and Onyx Wrist Band
Cobalt Lume Beads with Matte Black Onyx Beads strung on a flexible band. The matte black onyx has a very soft, dark sheen that is very different from our polished gunmetal beads. The cobalt lume is light blue during the day but glows a nice sky blue in the dark.
The glow works by charging in the sunlight, a UV light or a bright LED light. In sunlight or UV light it only takes 30 seconds to fully charge the beads. The glow intensity and duration is dependent on the darkness of the room. The darker the room, the brighter and longer the beads will last. Most people just wear these during the day and everytime they walk indoors, the glow effect will begin. Often some people keep small UV lights in their car or bag and charge it up before heading somewhere.
