2.Neodymium is a rare earth metal and it makes some of the strongest magnets possible. A single one of these tiny cubes is strong enough to be a refrigerator magnet. Handling them with care is necessary to prevent personal injuries, property damages and magnet damages. These cubes are so cool you can't put them down once you pick them up!
