Liquid correction fluid is a type of writing tool used to cover mistakes made on paper. It typically comes in a small bottle with a brush or applicator for easy application. The fluid dries quickly to create a smooth, white surface that can be written on once it has set. This product is commonly used by students, office workers, and anyone who needs to make corrections on printed documents or handwritten notes. Liquid correction fluid is often referred to by brand names like Wite-Out or Tipp-Ex, and it is a convenient alternative to using erasers or rewriting entire pages.
