Tiny firefly lights strung along a delicate copper wire - perfect for adding bright touch to any space, indoors or out. We love 'em for dorm decor, too! The LED bulbs are strung on a bendable wire with a water-resistant electrical adapter that is safe to use indoors or in a covered outdoor area. AC plug compatible, they require a power convertor when used outside of North America. UL listed; class 2 power supply 120v 50/60hz. Only at Urban Outfitters!
