I use these to magnetize the bases of my Warhammer minis so I can store them without sliding around and to provide weight to top heavy figures. They work great and are much cheaper than what I paid for similar magnets at the local hardware chain. They are thin and strong. I did have one that had a flaw on the side that made it slightly irregular, but it didn't impact the usage, so no issues for me. A little glue on the base and a few seconds later the mini is ready to be put securely in the storage box with the rest of my army.
