This is a viral marketing campaign for some kind of extra-fine point Pilot pen. I love the minifigs themselves, but the campaign bugs me for a couple of reasons: 1) I’ve been Googling around pretty hard and can’t seem to figure out exactly which of Pilot’s many pens these photos are promoting, and 2) nowhere does it explicitly state that the art on the minifigs was actually done with whatever pen they are advertising. So even if I could figure out which one that was, it’s not at all clear that I could actually use it to tattoo my own minifigs. In any case, any kind of super-fine-point permanent maker would probably work. [via Boing Boing]
