The Pilot V-Ball 05 is a rollerball pen featuring a conical tip and a durable tungsten carbide ball. It includes an ink regulator for a smooth writing experience. This pen lays down a pure, consistent line of densely-coloured liquid ink. The VBall 05 (extra-fine) writes a 0.3mm line, ensuring precise writing. It is known for its smooth-writing and reliably controlled ink delivery thanks to the V-System core.
