PITT Artist Pens are famous for combining a modern brush nib design with a tradition of India ink. India ink offers artists odorless, permenent, waterproof, lightfast inks with 48 vibrant colors. The durable nib gives the freedom to create verstaile ink brush strokes of broad, medium to narrow with an even application of color.
The Superfine, Fine, Medium, and Brush nibs not only replace ink bottles - they're instantly available for work. The ink is waterproof, unsurpassably lightfast, acid-free, and pH-neutral. The nib size is prominently displayed on the end of the cap.
