Neonetics Neon Signs feature hand blown neon tubing. The trumpet shaped neon sign features a plexiglass face and a single trumpet shaped tube of blue neon surrounding a silkscreen image of a trumpet. It can be hung against a wall or window, or it 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.
