Oil pens combine the advantages of ballpoint and gel pens: 1) ink dries instantly, does not smear, 2) moderate ink consumption, 3) soft writing, does not require pressure on the paper. In addition, oil pens are able to write at low temperatures, up to -20C. The body of the handle is made of durable plastic. A comfortable grip area with relief areas reduces hand fatigue when writing. Easy, smooth and accurate writing is provided by a high-precision Swiss writing node and high-quality ink. The writing node provides maximum adhesion to the surface of the paper and a uniform and uninterrupted ink supply, while the oil ink lays down smoothly, leaving an even, clear line. The rod has a standard length of 107 mm and a thin writing node - 0.7 mm. An ASR1028-A type rod is suitable for replacement. The length of writing is 800 m.
