Ballpoint pens feature 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. Barrel color matches ink color. Colors include black, blue, red, light green, orange, violet, pink and light blue. 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.
