Pens may fail to write on paper due to clogging of the ink flow, a dried-out ink cartridge, or a damaged tip.
Pens may stop working even with ink left due to clogging, air bubbles, or dried ink at the tip, preventing the flow of ink onto the paper.
Ink dries pretty quickly. Once the contracts have been signed, the ink is dry. I will note that historically, earlier forms of ink used by quill pens did not dry as rapidly as the kind of ink used in the modern ball point pen. Even then, the ink would be dry in a matter of minutes at most.
If it was completely airtight, then the pressure inside would drop, preventing ink flow. Placing a hole in the middle equalises the pressure and controls the flow of ink. The hole, basically, stops the pen from leaking ink.
Pens run out when the ballpoint nib can no longer transfer ink to the paper effectively. This can happen due to a combination of factors such as air exposure, ball wear, and ink thickness. Once the ink flow becomes inconsistent, the pen is considered empty even though it still contains some ink.
Multiple colored ink pens are typically referred to as multicolor pens or multicolored pens. These pens have multiple ink cartridges, each with a different color of ink, allowing users to easily switch between colors while writing or drawing.
A pen that is filled with ink is typically called an "ink pen." This term can refer to various types of pens that use liquid ink, including fountain pens and rollerball pens. These pens have reservoirs that hold ink, allowing for smooth writing.

Felt tip pens have a porous tip that allows ink to flow onto the writing surface. The ink is held in a reservoir inside the pen, and capillary action draws the ink to the tip when writing. The tip's fibers help regulate the ink flow and provide a consistent line thickness.
The ink inside a Bic pen is typically oil-based ink, which is designed to dry quickly and resist smudging. This type of ink is commonly used in ballpoint pens for smooth writing.
Some pens can be recycled but some can`t. Only plastic pens can. But you need to take the ink cartage out. GO GREEN!!!
