Great for do-it-yourself projects


Brand new and high quality,

Super strong Rare-Earth magnets – once they get stuck with each other, they are hard to break apart



Safe handling and storage of magnets

1 should always be very careful because the magnet will be attracted to their own together, you may pinch your fingers. Attract each other when the magnet may be damaged due to collision magnet itself (corners chipped off or knocked cracks).

Two would easily magnetized magnets away from items such as floppy disks, credit cards, computer monitors, watches, cell phones, medical equipment and so on.

3 magnet away from the pacemaker.

4 larger size magnet, should be added between each piece of plastic or cardboard spacers to ensure that you can easily
