This silly magnet looks like somebody threw a shuriken at your fridge, so strong it pierced the surface.
Effectively lets all your visitors know that you are a weeb. The black surface imitates that of untreated die cast iron, while the blades are brushed and polished, for strong contrast and a menacing appearance - the blades are however intentionally dull.
Diameter is 6.5cm (but the unit of measuremnt is meter)
