These are the Glowbys illuminating hair strands for a lady’s hair made of thin fiber optic strands easy attachable to the hair.
The effect in the hair is of tens of brilliant stars of light, more exactly 50-60 per Glowby.



Glowbys have the source two very small batteries and the strands can be found in several lengths and 8 cool colors, but more than that they are reusable if you change the batteries.
The illuminated strands don’t fade suddenly, but in time so you have enough time to get the new batteries, and this happens in about 11 hours of use.



If you want to turn them off you can do easily by sliding the lid slightly.
Oh, yes, and the price is of $10, but can find more on the product’s page here.
