Abstract
Disclosed is a ball point ink pen, its ink and its eradicator. The ink is carried at one end of the pen and the eradicator portion is carried at the other. If an error is made, the pen can be reversed and the eradicator used to neutralize the ink. The ink also neutralizes the eradicator so that when one rewrites with the same ink, any remaining eradicator on the paper is neutralized and the original ink acts as fresh ink.
