Wite-Out is a correction fluid used to cover mistakes made in writing or typing. It typically comes in a small bottle with a brush or a pen-like applicator, allowing users to apply a thin layer of the fluid over errors. Once it dries, it creates a smooth, white surface that can be written or typed on again. Originally developed in the 1960s, Wite-Out has become a popular tool for students, office workers, and anyone who needs to correct written documents. It is available in various forms, including liquid, tape, and pen, catering to different preferences and needs.
