You might have worn mood rings sometime in your teens. So, how about a LED nose ring this time! The Firefly nose ring is a magical piece of jewelery that glows when you breathe. The LED nose ring uses a delicate fan structure, that creates the delicate luminous pulses to glow when you exhale the air which transforms into electric energy, thus lighting up a led light. Though, you might have come-out of your teenage but sporting a funky look is not a bad idea at all! And, anyways this is uber-cool..isn’t it gals!!
