These amazingly strong magnets are the best magnets I have ever used and can handle any heavy scrap of paper I throw their way. We've got three different magnetic boards in the house (all three in areas off limits to the dogs, I know the dangers magnets pose to animals), and I'm always having to use three or four magnets to hold up a large piece of paper. These tiny magnets, however, have solved that problem. In fact, I wouldn't be surprised if these things were strong enough to pin an entire Thanksgiving turkey to a wall.
