Abstract A marking and/or highlighting and eradicating instrument having a marking and/or highlighting ink dispenser and an ink eradicator dispenser, which are coaxially and opposingly located each to the other and a barrel for manual gripping. Liquid dispensed from the eradicator dispenser removes the marking and/or highlighting previously dispensed upon a permanently printed surface. The marking and/or highlighting dispenser and the eradicator dispenser may each have felt wicks or other applicators for applying the marking and/or highlighting liquid and the eradicating solution.
