Cashing in on the enormous success of its Parker 51, Parker decided to create a more affordable version of the pen to reach even more customers. This pen is the Parker 21. One of the biggest differences between them is that the 21 has a steel nib, and the 51 has a gold nib. Our vintage pen is in good working order, complete with a working original pli-glass ink sac. Its nib is more of a fine-medium that has a little feedback at the tops and bottoms of letters. You should be able to see a big crack in the barrel where it threads to the section. Don't grip it too hard or use to much pressure, as you will get it to wiggle in your hand a bit. Click the headline for a close-up. 13.4cm capped.
