Correction fluid is a liquid used to cover mistakes made while writing or typing. It typically comes in a small bottle with a brush or applicator for easy application. Once applied, it dries quickly to create a smooth, white surface that can be written or typed over. This product is commonly used in offices and schools to fix errors on paper documents. It is often referred to by brand names like Liquid Paper or Wite-Out. Correction fluid is a convenient tool for anyone who needs to maintain a neat appearance in their written work.
