This fantastic correctional pen allows you to cover up your mistakes without drawing attention to them. The fluid is easily applied to the paper, with the nib giving you precise control over exactly what you cover. This makes it far neater than correctional tape or other fluid that is applied with a brush. The correctional fluid is designed to provide an even and easy surface to write upon, without blotting or causing more mess. This pack contains 10 pens with 8ml of fluid each.
