Today's post is somewhat of a hybrid between an entry in the "Review Revisited" and "Mini Collection" series. Since I've somehow managed to collect 5 or 6 of the Uni Jetstream 4&1 Multi Pens over the years, I figured I should revisit my last review and comment some on why I enjoy this pen so much. While I consider myself a multi pen enthusiast, I really use two on a daily basis: (1) the Lamy 2000 Multi Pen, and (2) one of these various Uni Jetstream models.
All of the various renditions of the Uni Jetstream multi pens use different materials in the body and grip section.
My Use Case For Multi Pens
Long-time readers of the blog know that I'm a fairly prolific reader and serial annotator, both in my day job and my personal life. For me, multi pens are one of the ultimate annotation tools because they allow you to mark up documents in multiple colors (different colors for different types of notes), and an added mechanical pencil option is a great bonus because it allows you to erase as necessary. The multi pen is a lifesaver when I'm traveling - particularly when I'm working on a airplane - as it eliminates the need to have multiple writing instruments available and minimizes the risk of something getting lost or falling under the seat. Multi pens are also great for when you want to read out on the patio, work on the couch, or another similar context in which you're not necessarily seated and/or writing on a flat surface.
If I had to pick a favorite to use daily, it would probably be the versions with the bamboo grip. It’s quite tactile and I imagine they will age/patina with time. The Karimoku edition is not bamboo, but rather reclaimed wood from furniture manufacturing, if I’m not mistaken. It also features a ceramic-like coating (possibly Cerakote or something similar).
What Makes a Good Multi Pen?
For me, because I’m not necessarily using this particular pen to write a novel, it all comes down to the refill and how reliable it is. While the Lamy 2000 Multi Pen (ok, "4-Color Ballpoint") might be one of the most versatile multi pens because it accepts universal D1 refills, I find myself using Uni Jetstream refills nearly exclusively in all of my ballpoints, so I've also managed to accumulate a significant collection of the Uni Jetstream 4&1 and 3&1 multi pens. These take a proprietary cartridge, but because I’m pretty much all-in on the Jetstream at this point, I don’t care as much. The "&1" refers to the added mechanical pencil - something the Lamy 2000 doesn't have.
The 4&1 contains four different Jetstream refills: black, blue, red, and green. All of them write smoothly. It can be extremely difficult to find decent ballpoints in colors other than black and blue, but the red and green refills here write a legible line and have been reliable over time. Jetstream refills tend to last forever without drying up, something that's especially important with a multi pen where you might not use a specific color on a daily basis.
While some might find the Jetstream 4&1 too large for their hand, I personally find it fairly comfortable due to its light weight. Uni makes this pen with multiple grip styles, however, so be sure to choose the one most comfortable for you. For example, those who tend to grip their pen hard might want to avoid the metal section models in favor of the gel grip, while the plastic and bamboo options present more of a middle ground.
Takeaways and Where to Buy
And this brings us to the "mini collection" portion of this post. At last count, I have in my personal collection six of these Uni Jetstream Multi Pens in various finishes: two of the standard Bamboo models, one model in the limited edition Karimoku finish, one metal-grip "Tokyo Bike" special release, one Tokyo Bike 3-color (no mechanical pencil), and a standard black gel grip 4&1. Five of the six pens are the 4&1 model, so I'm pretty much sold on that version. And yes, I know there are countless more editions and releases out there, but I can only use so many multi pens, and I plan to just pick them up as I come across them "in the wild" as opposed to tracking them down via eBay, etc.
If you’re interested in hearing more about why I like this pen, and multi pens in general, check out this YouTube video that I recently released that discusses how the Uni Jetstream 4&1 compares to other favorites, including the Lamy 2000.

In the meantime, in the interest of making this long-time personal favorite more accessible, I did order an assortment of the Bamboo-grip 4&1 Multi Pens for the shop. I currently have them in five muted pastel shades, including Mimosa Yellow, Oregano Green, Blue Grey, Gerbera Pink, and Sage. If you've never tried a good multi pen, this is an excellent place to start, given the combination of quality and price point ($25). The four included starter refills will last you a very long time, but if you think you might want more, or need to replace refills in an existing Jetstream Multi Pen, we sell all colors, as well as .5mm Uni mechanical pencil leads.
