Review: uni-ball Air, Rollerball Pen, 0.7mm

uni-ball Air

Between the name and the design of the pen, the uni-ball Air makes me feel like I’m writing with a Blackbird stealth jet. It’s a black, all-plastic rollerball pen with a faint hexagonal pattern on the barrel and a grey swoosh near the tip. It looks really cool.

The Air has a very interesting feel while writing.  It’s somewhat waxy on paper and is almost like writing with a crayon. The ink is very rich and dark, and it spreads out on the page so much that it feels much thicker than a 0.7mm tip. Though it doesn’t smear nearly as much as I expected, it does seem to bleed readily through paper.

One of the main advertising points of the Air is that it writes at any angle, and I think it actually produces a finer, cleaner line when writing upside down. If uni-ball offered the AIr in a smaller tip size, I’d probably jump to recommend it. At 0.7mm, however, it runs and bleeds enough that I’m inclined to pass it up.

    1. If it didn’t flow so heavy I think I’d like it a lot too, but I often use both sides of my notebook pages, so bleed-through ends up being a bigger deal for me.


  1. I’m finding the Uni-ball AIR doesn’t last very long; not like the old pens used to. Its not that I’m writing any more than I usually do – these pens last only about 6 weeks and there is no means of checking how much ink is in the pen to start with and how much remains. Is that a marketing ploy, I wonder. In this day and age of environmental conservation, I would rather use a commodity from a company that cares about the environment than their profit margins. You have a great product but please give us value for money and put the environment first. Thank you.


    1. Yeah, they are very wet pens – by that I mean, they leave a lot of ink on the page. You can get a nice, dark heavy line, but the ink will run out a lot faster.
