PILOT Hi tecpoint V7 Cartridge Pen (Black) Roller Ball Pen  (Pack of 6, Ink Color - Black)

The Pilot V7 Hi-Tecpoint Cartridge System Roller Ball Pen is the first liquid ink pen with a cartridge system. What sets it apart from other refillable roller balls is that the tip and ink feed don't have to be replaced each time the ink is refilled. Instead, it uses ink cartridges, similar to a fountain pen. This makes this pen more cost effective and environmentally friendly since you're throwing less of the pen away every time you refill it. You can refill the pen up to ten times with guaranteed smoothness. In addition, as part of Pilot's BeGreen collection of eco-friendly products, this pen is made of 71% recycled materials. The pen's Hi-Tecpoint roller ball in Pilot's classic needlepoint tip and liquid ink deliver excellent writing quality and extra bright colors, and its exclusive V-System regulator ensures consistent ink flow. The window on the side of the pen lets you see the ink levels
