uni Jetstream 4&1 Metal Edition, 0.5mm Ballpoint Pen (Black, Red, Blue, Green) and 0.5mm Mechanical Pencil, Dark Green (MSXE52000A05.7) (MSXE5200A5.7)

The material is a lightweight plastic, not metal. It doesn’t have a nice, heavy weight that I’d like, but some people prefer featherweight so to each their own. As for the use of the pens, switching out different colors is very seamless and the inks write just as smoothly. Since it didn’t come with any instructions, I had to look up a few things like how to replace the pencil lead and how to dispense the pencil lead. After watching a video reviewing this pen, it showed that you have to depress the clip repeatedly in order for the pencil lead to come out. I have included a video in how to use for your reference. Enjoy!

They are almost exactly like the Pure Malt version, except these pens don't have the wood finger grips. This pen and it's campanion pens are unique. The internal pencil and eraser is what's make them unique. These pens are the ONLY pen you need to have. I won't pick up anything else to write with! BIC has made a four color ink pen for a long time. However, it looks like a toy and doesn't have a pencil built in. No self-respecting business person would get caught carrying the BIC pen. The uni Jetstream will be a pen anyone would be proud to carry and show off. One more point, it's called the "metal edition", only the finger grip is made of metal. The upper half is made of plastic! I think some of the users who gave the pen low marks are kind of "cry babies." Most didn't shop very well and paid way to much for the pen to begin with. If you paid more than $16 to $17 for the pen, you paid to much! I've purchased DOZENS of these pens AND the "sister" pen, the "Pure Malt" version for as little as $15 to $16 each! For THOSE prices the pens are a GREAT buy! They do EVERYTHING you'd expect a pen to do, has a pencil and eraser built in and it looks great in your pocket and in your hand! AND, if you leave the pen laying around, when you come back to use it again, it will be gone! See if that happens with a BIC pen or some other single feature pen! Those pens you can't give away! I give these pens to my clients, friends and certain acquaintances, along with my business card. At first they all say they've seen pens like it before, I quickly tell them, "No you haven't!" I show them the wood grip, on the Pure Malt version, the four ink colors, THEN the pencil and eraser. THEN, they admit they've never seen a pen like it before! Just like I told them to begin with! Different colors of the same pen are available from Japan's Amazon store. However, shop carefully. For some reason the shipping charges are outrageous. Sometimes 3 to 4 times the price of ONE pen. NOT a good deal. I've found some vendors charging shipping charges about equal to the price of one pen and the price of the pen is a $1 or $2 LESS than the prices I find from USA sources. So I buy 10 to 12 at a time from Japan. The shipping is typically the same if you buy one pen or 10 pens. When you average the total cost against the number of pens received, I end up paying the $15 to $16 per pen!

Only half the pen is metal, the grip and the nose, the upper portion is plastic. Weight is light and not too heavy for a multi pen. Probably why they stuck with plastic, but I thought the metal edition would be an all metal body at least. I had some trouble trying to deploy the pencil when a pen tip was already out. I think my hand position was blocking something or the pen required a "break in period". I'm not having any trouble with it after a few days using it. The ink is acceptable. The red and blue seem to have more trouble randomly on certain pieces of paper? It is annoying because I haven't really come up with a solution that works. I don't have this problem with water based gel inks. It might be the paper, but I want my pens to write on a basic legal pad without issue.

I’m in my last year of medical school and this is hands down the best pen for any medical professional out there. Sleek and perfectly weighted the metal finish gives it a nice feel as well. Cannot recommend this enough!

I really like this pen. Four color pens in general seem to be pretty cheaply made, so I was searching to see if I could find a higher quality one, and found this. It says it is metal, but only part of the body is metal, but still that is more than most. However, even the plastic parts seems better built than the usual throwaway ones you find on these sort of things. And, in addition to the usual four colors of ink, this one has a pencil built in as well for even more convenience. Good product!

The metal is just some thin metal not good as I wanted this could break if you like twist it it is good tho but jut does not have a solid build

As a fellow Jetstream devotee (with the classic black in my arsenal), I was instantly intrigued by the 4&1 Metal Edition. Now, after putting it through its paces, I can confidently say it's not just another pretty pen. Sure, the sleek aluminum body is a major upgrade. It gleams like a knight's armor (minus the rust) and feels premium to the touch. But the pocketability, my friend, that's the real game-changer. Ditch the rubber grip, and you gain a pen that slips in and out of your pocket like a buttery dream. No more snags, no more frustrating fumbles – just smooth, swift access to your ink-slinging arsenal. But hey, this isn't just about looks and convenience. The jet-smooth Jetstream ink remains the star of the show. Black, blue, green, red – you've got all your bases covered for notes, doodles, and impromptu to-do lists. And that 0.5mm pencil? Sharp as a wit, perfect for quick sketches or jotting down those fleeting ideas. If you're a Jetstream fan yearning for pocket-friendly precision, the 4&1 Metal Edition is your new writing companion. It's stylish, practical, and packs a punch of color. Just be prepared for jealous stares from fellow pen enthusiasts.

Not only is this pen extremely smooth, it’s also very nice to handle. It has a premium metal bottom, and the top is reinforced plastic—which is honestly a good thing if you don’t want the pen to feel super top-heavy. It’s also very versatile: it comes with 0.5 Jetstream ink, but it also supports 0.7 Jetstream cartridges. It doesn’t include a 0.7 option out of the box, but if you order the cartridges separately, they definitely fit—I tested it myself.All colors are nice too.If you want to see more sketches I’ve done with this pen: @jjl_studio on instagram
