Magnetics come in two common sizes. 18″ x 12″ and 24″ x 12″. We can do anything from a single color on white background to full digital vehicle magnetics. We use the highest grade magnetic material and always round the corners so there is less chance of it falling off. We also only use 3m vinyl to avoid any cracking or shrinking over time. A well cared for magnetic can easily last 4-5 years plus.
