When Sheaffer introduced the Fineline cartridge pen in 1955, it marked another major player entering at the beginning of a revolution that changed fountain pen design as dramatically as the lever filler had in 1913. Until the arrival of easy-to-use, low-cost ink cartridges, all fountain pens were bottle fillers of one type or another. The only portable ink supply was a glass bottle that you had to carry with you. Sheaffer introduced converters a bit later than some competitors and has offered several types since the early 1960s.
