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 – Muji Hexa Ballpoint (.25mm Gel Pen)

My handwriting is very fine, and I always gravitate toward finer and finer tipped pens in my quest to jam as much information on the page as possible. But there is a limit to how small the tip of any given pen can be. Too thin a felt-tip will simply break, and ballpoints or Rapidograph-style pens will either not allow ink flow or damage paper. Thus, even pens on the smaller end of the possible scale are hard to come by (being more expensive and relatively user-specific when compared to more standard sizes), with .25 being about as thin as one can find. Muji, in its characteristic minimalist style, offers a gel pen in such a small size. Is it a worthwhile purchase?

As with many Muji products, the pen is outwardly pretty simple. The hexagonal black body is a little larger in diameter than a pencil, and covered in a matte rubber that is only interrupted by two slits in the plastic near the front (for seeing the ink level) and a set of bumps with the slightest of step downs for posting in the back. After a brief clear plastic part, the metal cone in the front quickly brings us to a very fine protruding ink tube that’s about an eighth of an inch long. The clear plastic cap is also hexagonal, with an integrated clip and matching color insert that both covers the tip and displays the sizing information where it can be read easily from a pencil cup. Other than this, there are no markings on the item itself, as the label comes off, stripping you of all its information(in Japanese).

Performance is good. The pen is comfortable to hold and stays firmly in one’s hand (though the material can make capping and uncapping a bit more “frictionful”). When put to paper, ink flows relatively smoothly. At this size of tip, it is impossible to eliminate all of the scratchiness, but a good job has been done of controlling it. Likewise, another problem at this thinness is that a pen will tend to skip more if at any angle other than perpendicular to the page, but this too has been mitigated. I’d still recommend you write as straight as possible, but it shouldn’t have too great an effect on the writing. I don’t have much information on the ink, but I can tell you that it dries quite quickly (I almost can’t get it to smudge) and it’s waterfast and alcohol resistant (it does bleed a little, but remains legible, which is good for writing and bad for stains). Its spread isn’t too bad either, laying out on the average page about the same thickness as a .25mm (01) technical fineliner (though, with my handwriting both seem very close to a .7 ballpoint).

The pen’s a good one. It’s nice and sleek with a rugged body (I might be worried about the longevity of the cap. though) and a good writing feel. It’s slightly more expensive than a gel pen of comparable quality in the States (the price tag says ¥210, or about $2, but they sell it in the US for $3), but not enough to be out of their range. The tip is noticeably more fine than other ballpoints and gel pens you’ll find, but in my opinion almost awkwardly so (I’ve never been a fan of how gel pens look on the page {when written with my hand}), and there can be potential issues with the pen drying out. Still, if you’re looking for a functional and minimal super-thin writing pen (that isn’t as finicky or fragile as a technical pen) this is one to look at.
