All magnets are not created equally.
Vehicle magnets greatly differ from the magnets commonly found on refrigerators.
The most noticeable difference is the thickness of the magnet itself.
We use 30 mil Magnum Magnetics for all of our car and truck magnets signs so you don’t have to worry about losing them when driving (common fridge magnets have the thickness of 16pt or .016″ or .4 mil).
Our most popular size is 12″ x 24″ but we also offer 18″ x 24″, 12″ x 42″, 24″ x 72″ and as small is 12″ x 18″.
Unfortunately we can not trim this product to a different size other than listed.
