Cons:
-Magnetism starts to decrease (and can be permanently lost) at 80°C. 
-Low corrosion resistance. (If the plating is damaged)
-Will rust when exposed to wet elements.
-Brittle (May break, crack, or chip upon sudden collisions with other magnets or metals.)
-Drilling magnets causes magnet to shatter. (Do not drill magnets as friction can cause fire / explosion due to flammable material.)
-Often higher cost choice.

To separate magnets, use a sliding motion, never try pulling magnets apart as it will cause them to snap together causing injuries. If you have larger stronger magnets use a wooden table or desk and overhang one magnet. Apply strong downward pressure to separate magnet from the other magnets. Once separated, keep moving the magnet to a safe distance.

If two magnets are placed loosely apart, they could leap together unexpectedly, with extreme speed and force, which could shatter and break both the magnets and could injure your finger if it is caught in between. Flying chips are sharp and could be a danger to your eyes. Handle only one magnet at a time.

Some of our magnets have a nickel coating. Prolonged contact with skin may cause irritation.

DO NOT allow children to play with magnets unsupervised and do not allow children to handle stronger magnets as they are powerful and will cause injury and could be fatal if swallowed. Magnets are not toys!

Magnetic Sensitive Items:

-Media: Keep away from credit cards and other magnetically stored media.

-Pacemakers: Keep magnets away from pacemakers. The operation of heart pacemakers may be affected by the proximity of a magnet. Magnets can set a pacemaker working in a way that is not suitable for the user and that might affect their health.
