STAR Atomic 12657 Glow-in-the-Dark Accessories, Nightglow, Blue,

Nightglow is a revolutionary device that uses rare earth crystals to absorb and then re-emit light through photoluminescence, a process never before seen before. Just 10 minutes of exposure to sunlight or a light will keep it glowing for over 10 hours. It can be used for over 10 years, making it versatile. The materials are non-radioactive and are safe for both humans and the environment. The housing is made of the same high-quality acrylic used in car headlights, protecting the rare earth crystals from UV rays and scratches. Color: Atomic Blue Package Weight: 0.01 kg
