There’s a ballpoint pen that’s incredibly useful for quick note-taking.
That’s the Tombow AirPress.
Despite how well it performs, it’s not very well known.
Honestly, I think it deserves more attention, so I wanted to properly introduce it here.
I often need to jot things down quickly for work, and I’ve been using this pen for a long time.
What is the Tombow AirPress?
The AirPress is a knock-type pressurized oil-based ballpoint pen.
Each time you click it, it compresses air inside and uses that pressure to push the ink out.
In other words, it’s a “pressurized ballpoint pen.”
What’s Good
1. Writes at any angle
Hearing “it writes at any angle” might not sound that impressive at first.
You might think, well, normal pens can do that too.
But actually, that kind of use puts a lot of strain on a regular ballpoint pen.
For example, when you’re writing in a notebook while standing.
The pen tip is usually horizontal, or even slightly pointing upward.
This angle can easily cause ink flow issues.
You know when a pen suddenly stops writing even though it’s brand new?
This is often the reason.
Regular ballpoint pens work by rotating a tiny ball at the tip to transfer ink onto paper.
But when you write upward, air can get pulled into the refill during that rotation.
So what happens?
You can still see the ink… but it won’t write.
A bit frustrating, to say the least.
At that point, you basically have to replace the refill.
Even though there’s clearly ink left.
The AirPress solves this in a very direct way.
By pressurizing the ink, it prevents air from interfering with the flow.
As a result, it writes smoothly whether it’s upward, sideways, or at an angle.
Apparently, it can even write underwater.
…Not sure when you’d need that, but it’s reassuring.
2. A well-designed clip for portability
The clip on this pen doesn’t get much attention, but it’s actually very well designed.
It uses a simple wire clip, but if you look closely, the left and right sides are slightly different in length and height.
That asymmetry creates a twisting resistance when attached, acting like a strong spring.
Because of this, it can firmly grip:
- Thin notebooks
- Thick work clothes
- Clipboards
It also opens quite wide, so you won’t run into the usual “this won’t fit” problem.
It’s a small detail, but very practical.
Pens that get these details right tend to be reliable.

3. Transparent design showing the mechanism
The clear body design, where you can see the internal mechanism, is another nice touch.
It’s a design that simply exposes the function, with no unnecessary elements.
If you like that kind of aesthetic, you’ll probably appreciate it.
It also adds a subtle accent when placed on a desk.
To be honest, this might be my favorite part about it.
What Could Be Better
No blue ink option
This is a bit disappointing for me personally.
I usually prefer blue ink over black.
It feels slightly softer and more intellectual, at least to me.
But the AirPress doesn’t seem to have a blue ink option (as far as I know).
And… why not?
It’s so focused on practicality, yet somehow misses this.
If they ever expand the lineup, I’d really like to see a blue version.
I mean that seriously.
Conclusion
The AirPress is a great fit for people who:
- Take notes while standing
- Work in tough environments like outdoors or on-site
- Often write in unstable positions
It might be a bit harder to find outside Japan,
but it’s sometimes available on Amazon.

It’s not the most famous pen,
but once you use it, you can tell it’s very well designed.
If you’re curious, it’s definitely worth trying.
