Translations:Resina plastica/8/en

Nowadays almost all pens are made in some kind of plastic resin, more or less shiny or resistant depending on the implementation. The evolution of technology also allows the creation of colorful plastics, whose brilliance and variety of colors has little to envy to celluloid. However, all of these are fully automated industrial productions, with a very low production cost, regardless of how someone can call them "precious". The celluloid long production times and the impossibility to process it by injection mold, made it a much more expensive material, and this is also why there was a return to it in recent years, as a distinctive feature of some luxury pens.
