Which filling systems for fountain pens are offered today?
Mainly, there are two filling techniques: the plunger system and the cartridge system (as a variation on the converting technique). The plunger system: the plunger refill is moved using a filler knob at the end of the shaft. This guarantees that the ink is economically absorbed out of the ink bottle. After filling, release a few drops of ink back into the bottle and then turn the filler knob to the closed position. The cartridge-system: Easy and clean to handle. The most common kinds of cartridges: The small standard ink cartridge (Pelikan = TP/6) and the giant ink cartridge (Pelikan = GTP/5). The variant converter: Makes it possible for you to convert a cartridge fountain pen into a plunger fountain pen. Instead of the cartridge, the converter is inserted into the shaft. The fountain pen can then be filled like a plunger fountain pen out of the ink bottle.
