Ballpoint pen with Viscoglide® technology for extraordinarily smooth, gliding writing. Extra Broad line width (XB). The ink dries quickly - even on smooth paper - and is smudge proof when highlighting it later on. The black ink is waterproof according to ink standard ISO 12757-2. Slimline design with an attractively decorated transparent barrel and clip cap that fits neatly on either end of pen. The rubberized grip zone provides a secure hold for relaxed writing. The wear-resistant stainless steel tip guarantees that the large ink supply can be fully used and does not smear. The Slider Basic is produced CO2 neutral. Each pack includes 8 pieces: black, red, blue, light green, orange, violet, pink and light blue.
