A correction fluid or white-out is an opaque, usually white, fluid applied to paper to mask errors in text. Once dried, it can be written over. It is typically packaged in small transparent bottles, and the lid has an attached brush (or a triangular piece of foam) which dips into the bottle. The brush is used to apply the fluid onto the paper. It can be used for many purposes.
