The Value of Owning a Set of Koh-I-Noor Technical Pens

For those who own a set of Koh-I-Noor technical pens, they already know how valuable they can be for any precision placement of ink to paper. The pens are available individually or in sets with different nib sizes. Tiny lines can be drawn with a nib size of 0.13 mm to broader sketch strokes using the 1.2 mm nib.

They are also known as Rapidograph pens. Available in 10 line width sizes, each pen is color coded for nib size and has a refillable ink vial. The pens offer a steady flow of ink across the surface of the paper, vellum, tracing paper and drafting film when the hand moves in any direction. This results in consistent line width that is essential for technical drafting and quite useful in art.

The Rapidograph pens are part of the Koh-I-Noor product line that includes drawing accessories, mechanical pencils, and Rapidosketch pens. The sketching pens only come in three nib sizes. A full set of 10 Koh-I-Noor technical pens are often as attractive to artists as they are to draftsmen. A full set of 10 Rapidograph pens come in a plastic case with a bottle of ink and a nib tool.

Some of the uses for the Rapidograph technical pens include:

Cartoon and graphic novel art
Tattoo design ideas
Precision line work
Lettering captions
Technical drafting
Precision crosshatch shading
Ink portraiture


Regular cleaning keeps these pens functional indefinitely. Problems begin when ink is left to dry inside the pens. This can be caused by long periods between uses or leaving the caps off. Cleaning is easy if the correct tools are used. Koh-I-Noor makes a pressure bulb cleaning kit that includes a squeeze bulb, nib tool and cleaning solution for cleaning pens. It is important only to use Koh-I-Noor ink that is available in black, red and white.

These technical pens are precision tools that have been in use by artists and draftsmen for years. If being able to draw lines in ink with an engraver's precision is important, these pens get the job done. In the hands of an artist, they can bring a new look to cartoons and other graphic arts, taking the work to the next level.
