If writing on paper and on touchscreen devices isn't enough functionality for your pen, this acupuncture pen lets you do "hand acupuncture". We're not quite familiar with this technique despite playing the five finger game with butter knives all the time, much to the chagrin of our wives. It's just a guess, but we're probably safe in saying that the pen doesn't actually pierce the flesh the way acupuncture needles do.
You should probably have some kinda training at this other than reading the included instruction manual, otherwise you're just poking yourself with a pen—something you can do with the ones lying around the house.
