Fineliner, 0,3 mm, EDDING "89 Office Liner", black

The line thickness of the fibre needles depends on the tip design. As a consequence, there are types, especially among the fibre gratings, whose line thickness is not a fixed value due to their cut tip, but falls within an interval. In the case of conical and needle-tipped pens, on the other hand, the line thickness is fixed.
