Our custom magnets - for vehicles or otherwise - can literally be cut to any shape and size. To do this you'll need to select the Custom or Custom with Border shape option when designing and ordering your magnet. The Custom shape option (previously known, or sometimes referred to, as Contour Cut) allows you to either upload a custom shape to our design tool or have us create a custom shape for your sign based off of your design. The Custom with Border shape option (previously known, or sometimes referred to, as as Halo Cut) is similar to the Custom shape option but will leave a small border around the edge of your design. Notwithstanding the ability to cut to shape, magnets that are not intricate in their design are more likely to adhere better to your vehicle due to the fact that there is less of a chance of wind getting underneath the magnetic surface while driving. You can also choose to keep the shape of your magnet as a square/rectangle or have it cut with rounded corners or as a circle/oval.
