Slider Basic Medium Ballpoint Pen features Viscoglide technology for extraordinarily smooth-gliding writing performance. Waterproof ink produces a medium line width for increased visibility and suitability for documentary use. Wear-resistant, stainless steel tip ensures that the large ink supply can be fully used. Ink dries quickly to prevent smearing and is smudge-proof when highlighting it later. Slimline design with an attractively decorated transparent barrel allows you to see your current ink supply. Rubberized grip zone provides a secure hold for relaxed writing. Clip cap fits neatly on either end of pen. Ballpoint pen is produced with a carbon-neutral process.
