Magnetic vehicle signs are great for vehicles .... until the last couple of years!  The newest thing on the market -- that is amazing -- is Removeable and reusable vinyl adhesive signs.  I would not have believed how good these work if I had not have used them - over and over.  These signs were designed when vehicles became more aluminum and less metal over the past couple of years.  All of a sudden the magnetic signs would not work.  These new signs can be made any size, can be printed as circles, squares or just a border around your symbol and wording. 

These signs are a little higher than the old magnetic signs but with proper care, can last a really long time.
