Leuchtturm1917 Drehgriffel No.1 Black Ink Gel Pen - Forest Green is a refillable, multiple award-winning pen manufactured in Japan.
In comparison to ballpoint pen ink, gel is thinner and flows more easily. Although the steel ball allows very even application of ink to paper, the ceramic ball of the gel refill delivers results that are more impressive.
The gel is also insoluble in water and therefore document-proof. The gel refill has a line width of 0.5 mm to produce a fine, yet clear written image.
