These 4 mm Neodymium Cube Magnets are deceptively strong. a cube of them can still be wildly entertaining as a stress-relief gadget. They are a great size for a bulletin board or your fridge, as just one of them will hold a stack of papers firmly in place, and they are large enough to grab and easily move. Fun, strong and sturdy!
