Neon Warehouse's neon signs in metal cans feature multi-colored, hand blown neon tubing. Each sign is 3 feet across, and the glass tubes are surrounded by a sturdy, commercial grade black steel housing. Your neon sign will come to your door suspended in a wood crate made especially to transport this giant neon sign. Unpacking instructions are included. All you do is hang it up and plug it in - no assembly or special wiring is required. These neon signs have a warm mesmerizing glow, and are powered by industrial strength transformers, which operate silently and more efficiently than incandescent bulbs.
