Rave retractable pen features ViscoGlide Advanced Ink Technology to provide an exceptionally smooth writing experience. The large 1.4 mm stainless steel ball enhances ink flow. These pens glide over paper like popular gel pens, yet dry quickly like a ballpoint. Great for lefties. The quick-drying waterproof ink also resists smearing when highlighting. The attractive, rubberized, ergonomic barrel reduces hand fatigue.
