Bests & Worsts Reviews from Amazon

I like the feel of the pen. I would like to be able to use it. It came with no ink, no instructions, nothing telling me how to extract I k from other pens to put in this one. Nothing about how to buy ink and put it in this one. I have a $15 paperweight and lightweight projectile to throw at annoying children. But I don't have a functional pen. Would have been nice to read in the description that it is inkless, would have been even nicer if there was an easy to find link to buy some ink, or a link to the instructions or something. Very disappointing as the top reviews were quite convincing.
