This is my 3d time from buying car magnets from Magnets on the Cheap. I have learned that you do have to store them in the box that they were shipped in, flat on the ground or a hard surface. Do not prop up because the magnets will slide down and fold/bend/crinkle and that is very hard to undo. To fix, you can place on a metal surface like a fridge and take smaller magnets to bend it back to shape. Nevertheless, I recommend this product.
