5 1/2" Car Cling
The solution for those cars that a magnet doesn't attach-- the removable sticker.  It's safe to paint.  We've tried it and it removes without any problem.  
Let the world know that you support ending pediatric brain cancer! People are seeing these magnets everywhere! They've been spotted from Maine to California, Missouri to Colorado, Spain to Canada, Illinois to Texas! Join us to help raise awareness for our mission.
And if you see one on the road, tag us on social media and tell us where! We are keeping track.
