Liquid-ink rollerball pens deliver smooth, consistent lines. The sophisticated, liquid ink feed system offers an effortless, skip-free writing experience. The permanent, pigmented ink helps prevent document & check tampering, as the ink cannot be lifted off the paper using common chemicals. Ink reservoir encompasses the whole barrel body for larger ink capacity & longer write-time. The texturized, rubber grip provides great writing control & comfort. Rubber does not contain latex, which causes allergies or phthalate (a potential carcinogen). Fade-proof, waterproof ink lasts over time & is designed for precise writing even through carbon copies. The Liquid Magnus Rollerball Pen also includes a durable, metal pocket clip to attach the pen to notebooks, folders & more.
