Review – Zebra SL-F1 Collapsible Pen

Earlier this year, my Fischer Space Pen Stowaway finally had the accident I was worried it might all along (the two halves of the pen became separated, and now I only have a cap). So, I needed to acquire some new small, daily carry pen. The choice wasn’t particularly difficult, my go-to ballpoint pen company, Zebra, has been making a collapsible pocket pen for some time and previously I simply never had an excuse to buy it. But, now that it’s in my hands, does it actually hold up?

When retracted the pen is absolutely tiny at just over 3¼ inches long. The rear part of the pen is a cylinder 7mm in diameter and just under 2 inches long. At the top of this tube is a flat chrome finial with a simple chrome clip extending just beneath it. At the other end of the tube is a slight polished step-down that leads to a smaller tube, at the end of that is a similar step-down leading to a polished metal cone. Grabbing the smaller tube and pulling forward slides it out from the larger tube about an inch. This action also retreats the cone a quarter inch into the pen and pushes the point of the pen out of the end (leaving you with an overall length of 4¼ inches). Both of these cylinders are constructed of metal with a matte black finish applied, and the only markings are the word “zebra” written in silver near the bottom of the larger barrel.

The retraction and extension method is a bit clunky and sticky, but it is very solid feeling and doesn’t show signs of failing anytime soon. The only potential problem I can see is that you need to be holding the tube that extends in order to write or the whole thing collapses back up again. The fine, .7mm ballpoint tip is, like all of Zebras refills incredibly smooth for a ballpoint while still having minimal skipping issues and providing a consistent and dark line (it writes almost identically to their standard refills for the “F” ballpoint series, but is a smaller, specialty refill). The extension of the pen is just enough to place it in the crook of most hands, allowing for it to be supported when writing, but the barrel/grip section, even for a lover of thin pens like myself, is small enough that your hand will cramp up over longer writing sessions (but this pen obviously wasn’t meant for that).

If you’re looking for a pen that maximizes space while still being rugged and usable, this is a definite winner. The metal construction is hardy, while the extending feature is handy. It is easy to refill by screwing out the front cone (preferably when collapsed) but remains safely in one piece throughout normal use. The clip is very grippy and sturdy while not being sharp or prone to rip fabric, and its situations so near the top allows for deep carry with very little sticking out above to get caught or seen (though this is actually a problem for where I use it, as I have a hell of a time getting it out of the loop I’ve stored it in on my belt pouch. Something like that shouldn’t be an issue for most people). The writing is very nice and smooth with a permanence suitable to most people even though it can’t write upside down or underwater. And the price, while certainly higher than most ballpoint pens, is not going to break the bank.

Review – Tombow Airpress

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.
