The Rotring 800 Ballpoint Pen features a heavy metal hexagonal barrel with a cylindrical knurled grip. Its unique retractable tip mechanism, activated by twisting the knurled control above the clip, makes the pen pocket-safe and protects against accidental sleeve damage. It has a 4mm fixed sleeve and a silver barrel. This refillable pen offers smooth writing, is long-lasting, and precise. It measures 144mm long with the tip extended and 133mm long with the tip retracted, weighing 25g. It comes supplied with a high-quality black ink refill in a simple card box. The full metal body provides an ideal balance of weight and feel for fatigue-free writing and drawing, while the hexagonal shape prevents the pen from sliding. The non-slip metal knurled grip is comfortable for frequent writing and drawing.
