The Tipp-Ex correction fluid is a white liquid. It is used for painting over mistakes in a piece of writing. A brush (which was later replaced by a foam applicator) is attached to the cap, so when the bottle is closed, the brush is immersed in the Tipp-Ex. When unscrewed, the brush is covered in liquid Tipp-Ex which is then painted over the mistake. However, it is still possible to see that Tipp-Ex has been used, and also the original content if the paper is held up to a light.

If the contents of a Tipp-Ex bottle have been exposed to too much air (for example, if the cap has been unscrewed too long or if the bottle is half-full and there is air filling the space), the Tipp-Ex becomes thicker, and sometimes even solidifies. To help prevent this, Tipp-Ex released a product called "Tipp-Ex thinner", a few drops of which are mixed with the contents of a bottle of partially dried Tipp-Ex to thin it. This extends the lifetime of a Tipp-Exbottle.
