Ballpoint pen features Viscoglide ink technology that is smoother than gel ink and a three-edge barrel for relaxed writing without hand fatigue. Ink dries fast and is wipe-proof even when highlighting. Black ink is waterproof. Triangular profile prevents the pen from rolling off the desk or other flat surfaces. Rubberized surface offers a good grip and promotes a natural writing movement. Wear-resistant, stainless steel tip delivers clean writing right to the end. Nonrefillable Slider Edge also features PVC-free construction, large ink reservoir and removable plastic cap.
