Liquid Correction, also known as correction fluid or white-out, is a handy office and school supply used to cover up writing errors on paper. Typically packaged in a small bottle with a brush or sponge-tip applicator, it allows users to paint over mistakes made with pen or printed text, creating a clean surface for rewriting. It dries quickly to a matte white finish, making it easy to write over once set. Ideal for neat note-taking, document editing, or any paper-based work, liquid correction is a practical tool for maintaining clean, professional-looking pages.
