Enjoy writing with a blue fountain pen but want to correct any mistakes? The ingenious LAMY Eraser Ink pen is double ended correction tool - eraser at one end, blue ink pen at other end. The eraser end can be used to quickly and easily erase any errors written in BLUE fountain pen ink (doesn't work on other colours or inks) and then you can overwrite your correction with the fine blue tip pen at the other end.

Note, this will only erase BLUE fountain pen ink. The eraser also does NOT erase the blue pen ink that comes with it, the pen is only for writing over erased/corrected areas.
