Neonetics Neon Signs feature multi-colored, hand blown neon tubing. The glass tubes are backed by a beautiful silkscreened full-color image, and the entire sign is supported by a black finished metal grid. The sign can be hung against a wall or window; they can even sit on a shelf. Neonetics neon signs have a warm mesmerizing glow, and are powered by industrial strength transformers, which operate silently and more efficiently than incandescent bulbs. All you do is hang it up and plug it in – no assembly or special wiring required.
