This magnet grabs metal so tightly causing the strongest person you know to be challenged trying to pull it off the metal surface.
Measures about 1x2", sold in a tray containing ten pairs of magnets, way below cost. Magnet thickness and color may vary from picture. Caution: These magnets are very, very strong and allowing them to crash together can cause them to chip or break. Do not store these magnets near computer monitors, hard drives, floppy disks, credit cards, or analog wristwatches-they are powerful enough to damage mechanisms and erase magnetic memory.
