Our Glossy Car Magnets are printed on heavy-duty material and ideally suited for car door signage. These glossy magnets can also serve as temporary signage for construction sites or other changing work environments and offer long lasting outdoor use. Choose round corners when ordering this item from the drop down menu if you prefer to have your car magnet to be more aerodynamic when using on vehicles. This could help prevent loosing your magnet when driving fast. However, our magnets are highly magnetized and hold up stronger than normal car magnets that you get from the market!
