uni JETSTREAM 4&1 Red, Green, Blue, and Black 0.7mm Ballpoint Multi Pen and 0.5mm Mechanical Pencil (Black)

Great fluid, consistent ink, makes writing easy. Hasn't leaked or bled yet. Love taking notes with all the colors. The grip could be more comfortable for me, it is a very thick pen, but that is probably unavoidable since it is 4 pens and a pencil in one.UPDATE: this pen is great, never bled or betrayed me. Weight of the pen is still a lot for me which causes sloppier note taking. I only used this pen for class work and it only lasted a single semester. The pen ink cartridges inside are very short and thin, so I wouldn't suggest using it for course work unless you happen to want to buy a new pen every 3 to 4 months or have found the same size ink cartridges for replacement.

This is one of the top two multi pens I have. The weight of the pen is well balanced ; it feels very much like the other leading brand. It also writes smoothly. Based on my experience, one of the strength of the Uni ballpoint pens is that its ink will not dry out over a long while. So I expect the durability will be excellent.

Great for taking notes and color coding them. The eraser is a little small but it’s nothing that can’t be replaced/fixed. The pen is very comfortable to hold.

Light construction but sturdy. Feels good in my shirt pocket. Very pleased to see that all the ink colors write very well and smoothly. The pencil clip is made well and stays put. The silver accents make it classy looking and the weight is enough that the pencil writes darkly. Very happy! Shipping was fast too. Would love a full size eraser but it is what it is. Will order again.

Not much to say here, other than the mechanism works well and the pen writes smoothly, unlike previous multi-color pens I've used. The mechanical pencil is a cool addition, although the skinny .5 mm lead is of limited use to me for writing. It feels a lot more solid than those other pens, and has what seems to be a thick metal lower barrel (although covered with a rubber sleeve.) It's a moderately hefty pen that sits well in my hand, and for $9 seems to be a very good deal. I hope it lasts long enough to use the refill set that's available on Amazon. (If not, I'll revisit the 5-star review.)

I really like the flexibility of the 4 color ink types, especially at work.Package arrived in perfect condition and on time. Thank You!

The Uni Jetstream 4+1 is an easy to hold, well-made, smooth-writing pen.I like that the black ink is black. Very black.I like that the blue ink is a dark, vibrant blue.The Green is the same shade of green as used on Universal Plotting Sheets, used for marine navigation. The red stands out as well.The ink cartridges can be "uneven" in that there's the occasional bad one.0.5 is good for notes.0.7 is good for general writing, and is my preference.The bold 1mm is a little more prone to smudge, but makes a subtle statement."Giftable" is not yet a word, but these make a good gift for anyone who has to make detailed, written notes,, logs, or has a carpal tunnel situation.

Such an improvement from the old Bic multi-colored pens of the past. Sharp colors, easy glide onto the paper, good looking, great for my day planner & notetaking, NO ink leaking through paper, EASY to move from one color to the next, comes in many nice exterior colors, it has a pencil op too which I have been using more than I expected..... I love this pen and it went beyond my expectations. It also DOES NOT SMEAR when I write and that is saying a lot as I am a left-hand writer and for those of you who are one/know one, this is a big deal. Another plus is that you can buy refills so the footprint is less wasteful. However, just like with anything, longevity is going to depend on how you treat your material possessions. It is not that you have to be delicate with it but do remember it's not meant to be ever-lasting. Treat it with respect & care and I am guessing it will last longer. Lastly, it is important not to compare this to a single colored pen. There are better writing tools for that. Remember the extraordinary capability of this particular pen is that THIS pen has 4 colors & pencil in one, so it belongs in its own category. If you judge by this, you may find yourself with the best of the bunch. By the way, I am a legit user, this is not a fake review, and now come to think of it...the company should really hire me. Lol. ps. I have only owned this pen a few days so if I get around to it I will try to do a follow up later this year.
