Set of 2 – 24” X 12” Car Door Magnets, Car Signs, Flexible Signs for Vehicles, White PVC Finish and Round Corners, Magnetic Thickness 30 Mil.

This magnet works great on my fridge, almost too good because I had a hard time getting it off... however, it would not stick to my car on the back. I am not sure if it's the material of my car or the strength of the magnet, but it did stick to the sides of my car, so I am assuming the back of my car doesn't contain enough metal to stick to it with the size of the magnet. Small magnets have no issue. Not faulting the product for my car's material. If your plan is to use this on the side of your car, then I definitely recommend.

These worked out great! Had them on my truck for 6 months just about . And even through the car wash they stayed on , (I forgot about them when going through) thay take vinyl very well . And they are thick. Love them and will order again

Not worth it. Did not work. Tried on multiple different cars all with metal door panels!

Strong magnet ... Held onto the door at high speeds and did not move ... Lasted about 2 years before started cracking in the West Texas Heat and sun.

We use these for our rescue signs and business signs. They stick well to metal, come in a bright white and look good, they are of good quality and handle vinyl well, the magnet is strong and holds well to our vehicles, and the quality is good overall.

This thing stuck to my truck like glue even while doing 85mph.

Worked great for covering rv vent, no more bugs in water heater while parked

These things fall off on the highway or interstate!
