You can customize your own magnets for your vehicles by following these simple tips:

Use legible font. Easy-to-read text is your best bet for any type of vehicle magnet. If your readers have to strain their eyes just to see your design, it might not get your message across in a clear manner. Avoid miscommunication or annoying your customers with lavish script that's hard to read. Use simple typefaces so that readers can easily understand what you're trying to communicate.

Avoid using color on color. This is not just for the sake of your customers but for your business, too. A message that's hard to read is also hard to understand. Like the first tip, this one can help send your message more effectively.
