These Pitt Artist Pens contain the same high-quality pigmented India Ink as the original Pitt Artist Pens, but with Big Brush nibs for full coverage or narrow, detailed strokes. Each Big Brush pen contains four times the amount of ink found in regular Pitt Artist Pens.

They are excellent for large artwork or for sketching, journaling, cartooning, and drawing. The acid-free, archival ink is smudgeproof, waterproof, and won't bleed through paper.
