Pentel Correction Pen ZL62-W 7ml

A correction pen is an opaque, usually white fluid applied to paper to mask errors in text. Once dried, it can be handwritten or typed upon. It is typically packaged in small bottles, lids attached to brushes (or triangular pieces of foam) that dip into the fluid. The brush applies the fluid to the paper.

Less commonly, the fluid’s fumes are inhaled to create dizziness, tachycardia and euphoria, sometimes producing adverse effects.

Before the invention of word processors, correction fluid greatly facilitated the production of typewritten documents. One of the first forms of correction fluid was invented in 1956 by American secretary Bette Nesmith Graham, founder of Liquid Paper.^[1] With the advent of colored paper stocks for office use, manufacturers began producing their fluids in various matching colors, particularly reds, blues and yellows.
