Review: If pens were crack these would be it - My favorite pen in the world , writes well , any angle, smooth ink , lasts a decent amount of time , no skips , if your a slow writer ink tends to bloom a bit on cheap paper , but if it’s good quality less so , great check writing pens

## Features

- 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.
- This set contains four blue inked pens, one of each of the following barrel colours: Pink, Orange, Green and Light Blue.
