Always be very careful, as the magnets will stick together and may pinch your fingers. When the magnets are attracted to each other, the magnet itself may be damaged by the collision (the corners are knocked off or the cracks are knocked out). Keep magnets away from items that are easily magnetized, such as floppy disks, credit cards, computer monitors, watches, mobile phones, medical devices, etc. Keep the magnet away from the pacemaker. For larger magnets, plastic or cardboard spacers should be placed between each piece to ensure that the magnets can be easily separated. The magnet should be stored in a dry, constant temperature environment as much as possible.
