Pacific Arc Ruling Pen - 3.5mm

Ruling pens are a precise drawing tool that are designed to create consistent and even fine lines. The two "jaws" of the pen can be loaded with ink, gouache, watercolour paint, or other similar fluid media.

Ruling pens are often used with technical rulers and french curves for technical drawings such as engineering and cartography. They are also a popular choice for calligraphy and picture framing.
