Designs and photos by Carol Ann Rice RaffertyGlowbys are fiberoptic battery operated barrettesGlowbys are illuminated thin fiberoptic strands attached to the hair (clothes, decorations, flower arrangements) to create many brilliant stars of light (50-60 fibers per Glowby, with the longest fibers 15" long). And you can cut to any length you want. There is a small barrette on the end that houses two small batteries and a light source, which lights up the ends of the fibers. The are reusable - you can wear them again and again. Available in rainbow (changes colors), blue and red (changes color) white, red, pink, green, blue and violet.
