Magnet Safety Warning
Please handle these rare earth 21 x 7 mm disc magnets with caution. They are incredibly strong and powerful for their small size, and can pose a safety risk.
These grade N52 disc magnets are difficult to separate by hand, and can snap back together with extreme speed and force. This may cause the magnets to break and send small fragments flying into the air, potentially causing injury.
With 28.3 lbs of pull force, these disc magnets can also pinch your fingers if they snap back together. For your safety, keep these magnets far apart and at a safe distance of several feet or more once separated. Hand and eye protection is strongly recommended when handling these magnets.
