Product Description: The revolutionary nib of the AIR, unlike conventional rollerballs, is pressure sensitive, meaning that it gives a writing experience and differentiating line width similar to that of a fountain pen. Featuring innovative Super Ink™, the uni-ball AIR is water, light, and tamper resistant, meaning that the ink cannot be washed off with chemicals or solutions used to fraudulently modify documents.
