The Rotring Tikky Graphic is a versatile fineliner pen with a metal-jacketed fibre-tip nib for precise, fine sketching and technical drawing. It's filled with non-fading, water-resistant pigmented ink, which flows smoothly and consistently, and has a useful ink level window showing the amount of ink left in the reservoir. The plastic grip zone makes it extremely comfortable to use. This set of three Rotring Tikky Graphic pens, all with black ink, contains a range of fine nib sizes: 0.1mm, 0.3mm and 0.5mm.
