I took some. That's how I lost it, actually... set it aside while taking pics in the hotel room in Sapporo and forgot it when I checked out. I'm at a Manga Kissa where I can't use my own PC, though, and the only way to get pics off my cam is through the built-in SD reader. (Camera has a stupid cradle thing, and it was too hueg to backpack around Japan)
It's a tiny thing... looks kinda like an oversized lighter, black with white printing, of a screaming Kaiji face and several ZAWA ZAWAs behind it. Slides open to reveal a little metal tray with a hole on top, and has a little carabiner on top to clip it on your whatever. Took me forever to figure out what it was, but I shat brix once I did.
Got a bunch of cool shit, though. They had Rozen Maiden phone/zipper charm things, with your birth month on them (and a day thing that came from behind the counter). Mine, august, was DESU DESU, which was epic win.
