Whito Pen

Whito Pen

A whito pen contains an opaque liquid, called a correction fluid, that can be applied over print and then written on again correcting the mistake. An invention by Bette Nesmith Graham, an American secretary who needed white liquid to cover mistakes made while typing with a typewriter. 

Various brands have their own mixture but all of them have a similar result. Once it dries the texture is also similar to paper, with a matt finish so it does not stand out too much in comparison to the page.
