Make sure your Ballograf pen lasts the test of time with this ballpoint pen refill. The tips are made from Japanese stainless steel and the balls are made from the extremely dense tungsten carbide. In the back of each cartridge is a small amount of fat which counteracts the ink to dry out even if the pen is left unused for a longer period of time. Both blue and black medium refills are certified Swedish archival quality which means that these cartridges with the medium tip are authorized to be used within local authorities because of their resistance to light exposure. Each cartridge writes 8000 meters and is suitable for all Ballograf Pens except Ballograf Pocket. Show more
