This product is used to identify and classify vehicles. For example, marking vehicles with the “customer waiting” hat would indicate that the customer is waiting for their vehicle or the “wash” hat would signal that this vehicle is in need of a cleaning. They can also be purchased with numbering on both sides or with a dry erase to finish to write on and wipe off your own message. These can be auto body shops, auto dealerships, car rental businesses, auto glass shops, and much more. Available in 4 vibrant colors to identify vehicles by department, team, status, and many other purposes. This item is sometimes referred to as Car Top Hats, Magnetic Toppers, and Car Top Cones.
