Translations:Cappuccio/10/en
Apart from some particular designs (the Pullman of Météore, the Asterope of Aurora and the Capless of Pilot) the cap remains one of the essential components of a fountain pen. The cap basically performs two functions, on the one hand it provides the protection of the nib against accidental bumps to the outside, on the other hand it protects the outside from accidental contact with the nib (and especially with the ink brought by the same) and from any leaks. A photo gallery of different types of caps can be found here.
