The OHTO Graphic Liner Rollerball Drawing Pen is a revolutionary new tool for artists and professionals alike. While traditional fibre-tip pens are often unreliable due to their changing tip size and ‘drag’, the Graphic Liner uses tough stainless steel and tungsten-carbide materials to ensure a consistent line width and smooth writing experience.

Unlike other pens, it has a hollow barrel that holds a generous amount of archival-safe, waterproof, and fadeproof pigment ink, ensuring no ink is wasted. With a durable polypropylene barrel and convenient stainless steel pocket clip, the Graphic Liner is an upgrade from traditional drawing pens in every way.

OHTO Graphic Liner is available with 6 different nib sizes. These are marked to compare with traditional fibre-tip pens. 005 smallest, up to 10. The actual rollerball tip sizes are as follows:

005 = 0.3mm tip, giving a 0.27mm line (writing length 1800m).
01 = 0.4mm tip, giving a 0.32mm line (writing length 1300m).
02 = 0.5mm tip, giving a 0.35mm line (writing length 1300m).
03 = 0.7mm tip, giving a 0.40mm line (writing length 1000m).
05 = 1.0mm tip, giving a 0.42mm line (writing length 1000m).
10 = 1.5mm tip, giving a 0.52mm line (writing length 600m).
