3-Piece Air Micro Roller Pen Red 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
• Will give you a finer line width between 0.25mm - 0.45mm, perfect for technical writing or small printing
