Notice of magnet treatment, storage and transportation?
a)Magnets stacked in close proximity to each other can exert great strength, therefore handle with care to protect your fingers and the magnets themselves.
b)Keep magnetized magnets away from the disk, magnetic cards, magnetic tape, monitors, watches and any other objects sensitive to magnetic fields.
c)Always keep magnets away from heart defibrillators.
d)To easy separation of stacked magnets always place a plastic or paper spacer between individual magnets.
e)Always store magnets in a dry and constant temperature environment.
f)Storage temperatures should always be kept below the highest working temperature of the magnets. Proper anti corrosion treatment shall be applied to uncoated magnets.
g)Magnetized magnets shall be shielded and packed especially for air transportation.
 
How long does the NdFeB magnetic characteristics last?
With their extremely high coercive force, NdFeB magnets will not demagnetize under  normal storage conditions. The magnetic characteristics will be maintained indefinitely, therefore, the shelf life of NdFeB magnets is not limited by time.
