Frixion pens use special thermo-sensitive ink that disappears when exposed to heat. The friction caused by the eraser at the end of the pen generates heat, making the ink vanish.

Erasable pens use special ink that can be erased by friction, typically with a built-in eraser or a separate eraser tool. This ink becomes invisible when heat is applied, allowing for mistakes to be corrected. Traditional pens use permanent ink that cannot be easily erased or corrected.
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.
Pens may fail to write on paper due to clogging of the ink flow, a dried-out ink cartridge, or a damaged tip.
Ink in pens can be made of various formulations, but common components include pigments or dyes for color, solvents to control viscosity, resins to bind the ink, and additives for specific properties like quick-drying or water resistance. Different types of pens (e.g., ballpoint, gel, fountain pens) may use different ink formulations.
Quink ink was invented by the Parker Pen Company in the 1930s. It is a combination of quick and ink, reflecting its dual purpose of being quick-drying and suitable for use in both fountain pens and ballpoint pens.
