These Glasses are Black Framed with Clear lenses so you can see what you’re doing even when you’re partying. The lights are made of the best, brightest, and most durable El Wire available. With the motion El Wire frames it appears as if the light is flowing around the lenses and you can control the speed with the battery pack! The battery pack is connected via a 4ft wire coming from the back of the battery pack and can clip to your belt, pocket, or backpack! 2AA Batteries are used to power the glow. If you’re a raver these glasses are an absolute must!
