These are amazing - I was so excited when I found these, and am so happy to share my find with you!!
This beautiful Fiber Optic Hair Clip has a spray of about 50 to 60 synthetic "Hair" fibers (The longest in the strands are 15", but they are cut in a cascade so that they flow beautifully. Yes, you can also cut them at any length - the light will shine from the end, wherever you cut it.
The brilliance is that the battery housing is SO SMALL! The little barette clip that attaches to your hair is only about an inch long. You can clip them over ponytails, Braid or style them into your hair, or clip them under your hair to hide the battery source.
*The color pictured is only to show you how they can be used - Each color glows brilliantly in it's own shade.
***The rainbow color is amazing because it does not just glow, but alternates colors and transitions in different patterns!!***
