Porous pens with metal reinforced tips define fine ink performance with a unique writing and drawing experience. Versatile needlepoint is preferred by those seeking the performance of a fine-tip pen with the ink laydown of a fine-tip marker. Acid-free, water-resistant ink formula dries quickly to prevent smearing and keep your writing legible. Plus, the archival-quality of the ink provides smooth, long-lasting color for the artist in all of us.
