Tibaldi still exists as a pen brand today in its third corporate iteration. You can also find some nice old vintage Tibaldi pens from the original company (founded in 1916) who made celluloid pens in the golden era up to around 1960. However, I have fallen for the celluloids made by the second version of the firm that started in the 1990s and had a relatively short life. They made some amazing celluloids in their short existence (and some questionable quality pens - I am looking at you Modello 60 with your captured converter), and once they shut down production the celluloid rods were sold off. These rods made it into custom pens, pens from other makers, and, once in a while, I will see a rod still floating about.
I am starting this thread for others who love Tibaldi celluloids to post photos of their pens, from Tibaldi to Edison to Conid to Bexley to Scriptorium to Newton to Stipula to who knows who else has made pens from these beautiful materials.
I especially love the Impero celluloid shown above and seek out pens made in the celluloid. Share your pens made of Tibaldi celluloid with the rest of us - vintage pens are welcomed too.
