Tipp-Ex

[3] Earlier, in 1951,[citation needed] Bette Nesmith Graham invented the first correction fluid in her kitchen and began marketing the product in 1956 as Mistake Out.

The system only worked if the typewriter repositioned the re-typed letter in exactly the same place as originally typed, which could be problematic if returning to a previous line.

Demand for this correction paper grew very quickly and brought interest from German and international distributors.

In 1992 Tipp-Ex introduced its first correction tape, followed in 1995 by the successful Pocket Mouse which worked as a best seller.

The range was extended to erasers, and in 2000, the new foam applicator was adapted to all the correction fluid bottles.

Gel ink will require a few seconds to fully dry, but can be used if no ball point pen is available.
