Among all their writing instruments, their roller-ball pens are infamous for smooth, crisp writing and the vibrancy of their colors – specially their black and blue. This review covers the three varieties of Uniball Eye – Fine, Micro and Needle, each pen for Rs. 60.00.

A roller-ball pen is a water or gel based ink pen that dries slower than the oil-based ink of the ballpoint pen. Depending on your writing style, a roller-ball pen could work for you if;

  • You prefer for ink to release at the lightest pressure.
  • You write quickly, since these pens are smoother than most.
  • You prefer your pen to not need any scribbling to activate
  • You use your pen for signatures.

Uniball Eye UB150 Micro – Available in Black, Blue, Red & Green
Uniball Eye UB157 Fine – Available in Black, Blue, Lt Blue, Violet, Pink, Wine Red, Red, Orange, Lt Green & Green.

All three varieties have a plastic bodies with a metal pen-clip and are single use pens. The ink barrel has some type of clear space on the print to be able to monitor ink levels. The top half, covered by the cap is clear so the ink dispersal mechanism is visible.

All inks are waterproof & fade proof and the nibs are made of tungsten carbide ball tips – for smoother writing. The blacks are deep and the other colors are vibrant. Like with many regular-use pens, they write better and smoother on regular paper than on textured drawing paper.
