My Tombow Airpress was presented to me in Japanese packaging, and, as such, I had no idea what it was supposed to do. Upon careful inspection of the pictograms, I came to a conclusion that was reasonably close to the correct answer of: it is a pressurized ink pen (so it can write upside down or underwater and such {think: space pen}), but it only gets pressurized when you depress the click mechanism. If or why this would be an advantage over regular pressurized systems I do not know, but the pen does come with a set of other features to make it more usable in the rugged outdoors and whatnot, so maybe you’ll get a greater value out of it. I’m probably not the target market here (my pens lead a very relaxed life), but let’s take a look anyway.

The body of the Airpress is cigar-shaped, with a rubber coating, and quite short at less than 5”. An eye-shaped indent in the middle of the pen and six plastic flutes on the section expose the inner mechanism so that you can see a little bit of what’s going on inside. At the front, there’s a removable cone (which is where the pen gets refilled) that tapers down to where the ballpoint gets exposed. Up near the back is a plastic area, attached to which is a weird-looking wire clip (with a plastic end for extra grip), and protruding from it is the click-button. Sitting opposite the clip is a clear-plastic lanyard hole. The identifying markings are hard to find, with “Airpress” being molded into the rubber and “Tombow” “Japan” very minute in the plastic around the mechanism. Still, there is enough there for refills or replacement if you need it.

The tip is a little finer than the average medium ballpoint and writes smoothly enough, though I do find it has a problem with blobbing or bits of dried ink on the end like many of the pressurized ink cartridges. It is indeed capable of writing upside down (or without gravity) and underwater (which also proves that the ink is waterfast) with no noticeable effects on performance. The body is rugged and tough (though I don’t put my pens through terribly destructive situations) and the rubber coating allows you to maintain a solid grip throughout use. The clip is quite grippy, with the plastic attachment having several ridges that catch as it clips, and the wire design allowing it to open to almost a 45-degree angle without deforming or breaking. (I haven’t “tested” the lanyard hole, but it seems to be fine)

Everything about this pen is pretty solid. It’s easy to write with, easy to hold (it’s quite chunky and a little thicker than I like my pens, but some people prefer that and it’s better for the use case of this pen in particular), and well built. The clip and the click mechanism are both satisfying to use and the rubber is solid while lacking that sticky-feeling rubber can sometimes have. All of this comes in a very portable package at a decent price (cheaper than your average Fischer Space Pen), which makes it something ideal to look at for someone in one of the various “rugged” professions or as a reliable EDC (everyday carry) pen.
