Overview

An illustrator, manga artist or technical drafter gets a set of black pens in graded tip sizes here, from very fine line to brush, filled with waterproof archival pigment ink.

Graded tips let one set cover outlines, hatching and detail work, and the waterproof archival ink is named as suitable under watercolor. The limitation is mixed labeling and a short cover period, with surfaces limited to paper and cardboard.

Who it's for

A drawing desk where line art, sketches and outlines are inked before watercolor or coloring. Colorists and anyone needing non-paper surfaces should look at other pens.

Pros and cons

Pros
  • Graded tip sizes
  • Archival pigment ink
  • Brush tip included
  • Suits many drawing styles
Cons
  • Black ink only
  • Labeling mixes marker types
  • Paper and cardboard only

Performance notes

Pigment ink dries on the paper surface, which is why waterproof archival pens pair with watercolor washes. Tip width sets line weight, so fine tips suit detail and wide tips suit outlines and fills. Light strokes protect fine tips from wear.
