Everythingneon Neon Signs feature multi-colored, hand blown neon tubing. The Corvette C2 Stingray neon sign has red, white and blue neon tubes, and has a 24 inch diameter. The glass tubes are backed by a beautiful 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. Everythingneon 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. For Indoor use only.
