uni-ballAIR Micro - 0.5mm Fine Rollerball - Blue Ink - Pink Barrel - Pack of 3

The ink flows well. They are comfortable to write with. As with most pens with this type of ink the ink will speak through the page slightly but I was fully aware of this before purchasing and I’m very happy with them. Good value for money

I love a blue pen and these are a joy to write with. VEry smooth and dependant on the angle you use when writing changes the thickness of the ink.

Runs out of ink to quickly
