Black uni-ball Air Rollerball Pens feature a tip that minimises the friction from contact with paper, providing an extremely smooth writing sensation that is scratch free. The air tip gradually adapts to your writing style and releases ink depending on the pressure applied, creating a varied line width. The 0.7mm tip releases black waterproof ink and allows for a light and smooth writing experience.
