Uniball 12-Piece Air Medium Rollerball Pen Set, 0.7mm, Black

The nib's metal ball is encased in an acetyl plastic, rather than a standard metal perimeter, allowing for a smoother flow of ink around the ball, and increased flow when more pressure is applied.

Features:

• The revolutionary air tip, unlike traditional roller balls, is pressure sensitive, which means it gives a writing experience and line width distinction similar to a fountain pen.
• The nib's metal ball is encased in an acetyl plastic, rather than a standard metal perimeter, allowing for a smoother flow of ink around the ball, and increased flow when more pressure is applied.
• The 0.7mm ball provides a line width between 0.35mm and 0.55mm (depending on pressure).
• Featuring UNI's high-quality "premium ink", it is not only water- and light-resistant, but also "smudge-proof", meaning that the ink cannot be washed off with the chemicals and solutions that people use to modify documents incredibly.
• The box contains 12 blue ballpoint pens.
