Ballpoint pen with Viscoglide® technology for extraordinarily smooth and gliding writing. Writing colour black. Extra Broad line width (XB). The ink dries quickly - even on smooth paper - and is smudge proof when highlighting it later on. Waterproof according to ink standard ISO 12757-2. Ideally suited to drawing and painting projects because the special ink will not run even on absorbent paper. A generously rubberised three-sided barrel is designed for relaxed writing without hand fatigue. It does not roll on the desk and its slim shape fits perfectly into school children's pencil cases or into desk pen drawers. The cap fits neatly on either end of pen. The wear-resistant stainless steel tip guarantees that the large ink supply can be fully used and does not smear. The Slider Edge is produced CO2 neutral.
