BARMP!BARMP! Bumper Magnet

One of my all-time faves is the NL version of car horns. "Barmp" is the best. 

It's the classic bumper sticker shape, but in magnet form. Meant to last through all sorts of weather. Black with white text. Measures approx 3" high by 10" across. 

Note: I've only tested this on my own vehicle. Vehicles are made with all sorts of different materials, so I can't promise where it's going to stick or not stick. On my Honda CR-V, it stuck perfectly to the side doors and to the main part of the back door. 

Update: Also tested on my Dad's Silverado, lol. It sticks to the front and rear bumpers, but not the doors. It sticks to the pan of the truck, but not the tailboard.
