Ninja Throwing Star Magnets
Part mercenary weapon, part magnetic field holder for your grocery list, these high quality magnets will hold up to a sheets of paper firmly against your refrigerator or any other metallic surface. Most crappy fridge magnets are either too flat to make removal easy or too weak and end up sliding down or falling of the fridge door. And nobody likes bending over (squat, don't bend!).
And, it also looks pretty cool to have Ninja throwing stars embedded into your fridge door.
