The Liquid Magnus roller ball pen contains water- and fade-resistant acid-free liquid pigmented ink for the exceptionally smooth writing experience of a gel pen combined with the strength and durability of a ball point pen. Permanent pigmented ink helps prevent document and check tampering, as the ink cannot be lifted off the paper using common chemicals. Designed for precise writing even through carbon copies, these pens write with clean, distinct lines. Visible ink supply helps monitor ink levels over time. Ink reservoir encompasses the whole barrel body for larger ink capacity and write time. The texturized rubber grip provides great writing control and comfort, while not containing latex or phthalate. Color coded end cap includes flat metal clip.
