Uni-Ball AIR Micro - 0.5mm Rollerball Pen - UBA-188-M - *Buy 2 Get 1 Free*

  • 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.

  • Available in Black, Blue or Red

  • Buy 2, get 1 free! Simply add any 3 to your basket and the discount applies automatically.
