My experience agrees with Deb's. Celluloid pens of high quality such as from Conklin Toledo (not Conklin Chicago) shows no shrinkage and looks amazing even today. Shrinkage is more of a problem for plastics *after* celluloid is not longer used.
Another example is Parker Vacumatic, one of the most popular pen in the world, is made with celluloid and having restored a lot, I've yet to see one with shrinkage problem.
About the only irreversible problem with some celluloid is the "crazing" that you can see on some Wahl Eversharp pens, which is a big pity because their pens are beautiful.
Gosh, what a lot we got.
Thanks to all contributors.
I see that Cult Pens currently list Platinum #3776 made from celluloid. I had thought it not used any more because of the spontaneous combustion problem with cine films.
Modern celluloid is cellulose acetate, which is more stable than vintage cellulose nitrate (the potentially explosive/flammable film stock kind). Wiser heads than mine can explain why, and which kind Platinum uses. http://www.fountainpennetwork.com/fo...-of-celluloid/
OMAS, from 1938, no discoloration, no shrinkage

There are currently no modern pens made with funky materials such as Casein, correct?
A big thank you to all contributors. I think it time to revise the list

I'm still searching for a pen made with pure unobtainium.
Leathers and lacquer are only coverings on top of other materials of which the pens are made.
Back to the first post of the thread :
I was wondering what materials the barrels and caps of pens can be made from or covered in.
I know that it's a very wide description.
Now there's something different. A concrete pen.
Thank you for the information. I am going to have to have one of those.
That reminds me of this Visconti made with resin and terracotta compound:

I've never seen a pen with that sort of topographical 'contour' design but I love it. It looks large and is quite heavy as you'd expect (45g)!
There are also a lot of alloys used such as Nickel Silver for instance in the caps of some models of the Aurora 88p
Its an alloy of copper nickel and zinc (no silver)
