These Pitt Artist pens contain the same high quality tinted Indian ink as the original Pitt Artist pen, but with large brush tips for full coverage or narrow, detailed strokes. Each large brush contains four times as much ink as the average Pitt artist pen.
They are excellent for large artwork or drawings, journals, cartoons, and paintings. Acid-free, archival ink is stain-proof, waterproof, and will not bleed out of paper.
