It's meant to be used in a magic trick somehow; one side of the pen has a fake point on it, attached by quite a strong magnet. I think I remember David Blaine doing a trick poking a pen through a dollar bill, and I suspect this is how he did it, but I haven't figured out how yet; there weren't any instructions.
As a pen, it works fine; it has a very fine nib, and writes well.
Overall, it cost just a few cents more than a Euro; great value. Free delivery, within the promised time. Thanks MITB!
