12-Piece Air Broad Roller Pen Black Ink

Highlights

• Freedom of a fountain pen with the security of a roller-ball with no leaks, the Air’s unique metal ball can move without friction when the pen is held at an angle
• Filled with Uni-Ball Super Ink, an advanced ink formula that bonds to paper fibers, fade resistant, water resistant, and acid free, resistant to chemicals that wash dye-based ink from checks
• Light pressure will give a finer line as ink is transferred by the ball itself, firmer pressure allows the ink to flow freely around the ball for a thicker line
• Average line width between 0.355mm and 0.55mm when varying with the pressure applied, making the pen perfect for writing or calligraphy
