Are they hard to install?
Not at all!
Sketch & Etch Neon signs come ready to hang, with pre-drilled holes. If you can hang a picture frame, you can hang a Neon! Read more about our Neon sign installation here.

How do Neon signs work?
Your Neon will come with an adaptor suited to your delivery location, and a remote control and dimmer. All you need to do is plug it in to a power socket, just like a lamp. Then all that's left to do is turn on and enjoy! Plus, you can adjust your brightness with the remote control. Please note, your Neon will also come with approximately 3 metres of translucent cord which connects to your Neon sign, this then connects to an additional 2m of black cord and your power pack.

Quality and care
We pride ourselves in exceptional quality, and happily offer an extended 24 month manufacturers warranty (double the industry standard!).
Please note, all Neon art in our shop are intended for indoor use only.

Show stopper!

Not only were the team from Sketch & Etch helpful with my questions. The quality of the stock and the speed it took to arrive was amazing. Could not recommend their products more.
