What To Do With A @Retro1951 Tornado Tube?

If you happen to have a Retro51 Tornado pen, you probably have one of these tubes. Unless you have one of the new ones... but if you're a true fan, you already have one, so you have one of these tubes. In which case, you can reuse it. I have used mine for several things that are not entirely useful but they're fun. Such as: toting ink sample vials, and toting loose tea.
