Faber-Castell PITT artist pens contain highly pigmented water-based India ink that is permanent and waterproof once dry. They do not bleed through paper, and the ink is lightfast, odorless and archival.
Pitt pens may be used on any porous surface like paper, canvas and wood, for drawings, sketches, layouts, fashion design, illustration and more. The range of nib sizes availble make the Pitt an extremely versatile pen, and very popular for mixed media work.
This white pen has a 2.5mm bullet tip that works beautifully on dark papers, as the video below shows.
