Looking for a cute baby on board magnet? This is perfect for you! Choose from three colour options for this magnet that can be easily placed on your car and easily removed. These magnets will only work on cars that are metal! If your car is made of another material such as plastic or fiberglass, the magnet will not stick. To test if your car is made of metal, take a regular magnet (like one from your fridge) and see if it sticks on your car! We sell baby on board bumper stickers as well if your car is not metal. We recommend removing the magnet when washing your car or during heavy snowfall. Each magnet is approximately 6.5” x 3.25”
