We'd bought some beautiful pens as Christmas presents for family, but wanted a novel way to package them. I designed this screw top tube which is pretty and functional (and long term re-usable - which is more than can be said for most wrapping paper).This case is 16cm long and can hold a pen no longer than 14cm. It does scale well (as I found when I realized one of the pens had a wider diameter) but ensure you scale both lid and body otherwise you will have problems with the threads.
