Celluloid can be a very durable material, but it requires a rather lengthy process in particular for drying that allows you to remove residual moisture from the material. If this does not happen in fact it can give undergo a crystallization, becoming extremely fragile. Another common problem with celluloid pens is the discoloration, present mainly in the lighter colors such as pearl or jade green; this is typically due to the release of sulphurous gases from the rubber sacs. Furthermore, the celluloid is extremely flammable, and is not the case to heat a celluloid made pen with an open flame.

Il nome celluloide è in realtà il nome commerciale dato a questo materiale dal primo produttore, la ''Celluloid Manufacturing Company'', che deteneva i relativi diritti sul marchio; per cui negli anni successivi sarà chiamato, in particolar modo dai vari produttori di stilografiche, nei modi più diversi: ''[[Radite]]'' dalla [[Sheaffer]], ''[[Permanite]]'' dalla [[Parker]], ''[[Pyroxalin]]'' dalla [[Eversharp]], ''[[Aurolite]]'' dall'[[Aurora]], ''[[Coralite]]'' dalla [[Carter]] ...

The celluloid name was the trade name given to this material from the first producer, the ''Celluloid Manufacturing Company'', which held its trademark rights; so in the following years it was called, especially by fountain pens manufacturers, in many different ways: ''[[Radite]]'' by [[Sheaffer]], ''[[Permanite]]'' by [[Parker]], ''[[Pyroxalin]]'' by [[Eversharp]], ''[[Aurolite]]'' from [[Aurora]], ''[[Coralite]]'' by [[Carter]] ...

Oltre all'uso diretto, la celluloide si presta alla combinazione con altri materiali, in particolare la [[Carter]] realizzò un caratteristico materiale iridescente, denominato [[Pearltex]], combinando la celluloide con madreperla. Un effetto simile si trova nella celluloide denominata ''[[Abalone]]'' dalla [[Sheaffer]].
