If you prefer the smoothness of a fountain pen with the no-hassle ease of a ballpoint, then this luxurious Parker Duofold rollerball might be for you. Rollerball pens are like ballpoints, only they use cartridges with water-based fountain pen ink instead of the oil-based ink refills of a ballpoint. This preowned pen is based on the vintage pearl-and-black Parker Duofolds of the late 1920s. We include a brand-new black refill with the pen. Our pen shows a little wear from use, but it remains in attractive, great-working order. It has a 1994 date code. It is doing great for 30 years old! 13.1cm capped.
