Let's say, hypothetically, that you have a lot of pens. Like, so many pens. Let's also say that you want to keep at least one of those pens close at hand on your desk, but you worry about it rolling away or getting shuffled under some notebooks (of which you also have many), and storing it nib-up in a pen cup tends to drain the feed. In that (hypothetical and not at all a self-insert) situation, you might just be interested in the Penwell.
