I was sent assortment of products to try out. I think they are very cool hair clips and that its nice that you can cut the fiber to the length you want. If you do cut them, be sure to cut them at a 45 degree angle. They light up really bright and are easy for kids to use. Make sure when you dont have them in you turn them off. To do so slide the barrette lid open to close.

Luminence
Hair lights are illuminated thin fiber optic strands attached to the hair to create many brilliant stars of light (50-60 fibers per Glowby, with the longest fibers 36cm long). The extremely compact,two small CR1220 batteries (BATTERIES INCLUDED) and a light source, which lights up the ends of the fibers.
GLOWBYS ARE REUSABLE – you can wear them again and again. Just change the batteries when Glowbys become too dim, typically +10 hours. Slide lid slightly open to turn on/off. Perfect for Mardi Gras, the prom, Christmas, St. Patrick’s Day, nightlight, Halloween, and more.
