Kim,
Remember Wayne Bobbitt? You know, the one who had "something special" cut off by his wife?
Well, those "pens" you're looking at are really "bionic replacements" (with such enhancements as vibration) for what he had cut off, however, the "pens" work even though they aren't "attached" to a man. Thusly making them attractive to "unattached" women...
Another way of looking at it: if you added an " i " as the fourth letter of "pens", you'd get a much better idea of what they replace...
