You get a lot of them and they are really, really strong for their size. I bought them to help hold parts to the metal base on my drill press and it works great for that. I also put a couple in my daughter's bubble bottle so that it doesn't tip over when she's using it. Again, works great for that.The big downside is that these are incredibly brittle. They are so strong that they snap to anything metal and the force tends to break them. The shards of the magnet are sharp.
