Erasing pen from paper is the process of removing ink from a paper surface without damaging the paper itself. There are various methods to achieve this, depending on the type of pen used and the age of the ink.
One common method is to use an eraser, which is a tool made of rubber or a similar material. Erasers work by gently abrading the surface of the paper, lifting the ink particles away. However, erasers may not be effective on all types of ink, especially permanent or waterproof inks.
