So, how does a Fountain Pen work?
A fountain pen works by using a combination of gravity, capillary action, and pressure created by the user's hand to move the ink from the reservoir, through the feed and nib, and onto the paper. Gravity pulls the ink from the reservoir, down into the feed. The feed is a small tube that connects the reservoir to the nib. The nib is a metal or plastic point that has several small channels that allow the ink to flow onto the paper. Capillary action then causes the ink to flow through the feed and nib, and onto the paper. Finally, the pressure created by the user's hand on the nib helps to further increase the ink flow.
