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