Plain Magnetic Bumper Medium is great to use for attaching bumper stickers to your car. You simply peel and stick a bumper sticker you already have to our material, and then slap on any metal surface on your car. Plain Magnetic Medium wont damage your paint, and makes it easy to take your bumper sticker on and off. Note also our Custom Bumper CarToo where you send us your artwork and we create the entire CarToo printed, cut and UV protected. Either way you cant go wrong.
