The Free Ink Roller combines the advantages of a ballpoint pen and a fountain pen. The roller tip is made of metal and able to withstand extreme loads, thus allowing intense writing pressure. At the same time, the even ink flow provides an agreeable writing action. The roller is available in two different line widths (EF and F). Depending on the line width there are 4 to 10 colours available.
