Uni-Ball - 0.5mm Fine Rollerball - Blue Ink - Pink Barrel - 6 Pack

• 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. • The metal ball of the nib is encased in an acetal plastic, rather than the standard metal surround, which allows for a smoother flow of ink around the ball, and an increased flow as further pressure is applied. • The 0.5mm ball delivers a line width of between 0.28mm and 0.45mm (dependent on pressure). • Features Uni's high quality "Super Ink", which is not only water and light resistant, but also "Tamper-Resistant", meaning that the ink cannot be washed off using chemicals and solutions used by people to fraudulently modify documents. • Pack contains six Blue inked pens, with Pink coloured barrels.
