Coincidentaly, I was making a retro today and made a Jr Gent yesterday and was photographing them together then saw this thread so thought I'd share. I use what I consider to be the finest non-wood box available and I get them from Craft Supply. Penn State and their resellers also carry the same box.
So for comparison sake, here are a Jr Gent and a Retro side by side and a nice box that will hold the Retro as well as all of the larger pens, Statesmen, Majestic, Emperor, etc.
