Be careful with this magnet. Once you place it on your fridge or other metal object, it must not be removed until you are ready for it to detonate. So before you put it down, think carefully and make certain you’re putting it in exactly the right place. Otherwise, you’ll be stuck with a suboptimally located magnet for the rest of your life. Apologies, apparently this is in fact only a magnet SHAPED like a grenade. Go ahead and put it wherever you want. If you dare.
