Storing your magnets is easy, simply place back on a refrigerator or large flat steel surface. Storing in a clean, dry environment, ideally on a leveled smooth steel surface. Not on the seats of a car or in a trunk, since it is not flat and can easily exceed 150 Degrees F. Make sure to not place objects on top of the magnet to try and flatten or stack two magnets with the magnetic material facing each other, this will cause it to demagnetize.
