Deadly Weapon Fridge Magnets

A set of 3 super deadly fridge magnets: a sword, a knife and an axe. They add a certain level of macabre to those photos on the fridge!

They're actually kind of small for the $8, but still really cool. Don't expect them to hold up more than a single piece of paper, but they do the job.

Magnets, how do they work? We can only assume that they're complete magic.
