So the wall set that comes with displate posters is terrible! You attach a large, thin magnet to a piece of paper that sticks to the wall, not a bad idea, but the paper isn't very sticky, and since the magnet is so thin, it needs to attract the center of the poster magnetically. because there is a gap between the poster and the magnet, which in turn will pull the paper away from the wall and the poster will fall off between a few hours and a few days. the gap between the poster and the magnet, and so far has managed to stick to my wall and it's been a few days. The only thing is that I had to position the magnet vertically as it seems to support the weight of the poster (posters are steel).
