Review: One of the best quality pen in my collections - Compared to many high quality pens, this is one of the best. Nice grip, smooth writing feel, and reliable performance. Multiple color plus pencil. Best for making notes with drawing!
Review: This is a REALLY nice pen. - So, I decided after years of reviews to go with a Uni Jetstream. I bought 3 versions - the 4+1 Prime High-grade, the (metal edition of the) 3-in-1, and the cheap plastic multipen. You clearly get what you pay for. This 4+1 prime is a REALLY nice pen. Well balanced, smooth, quality metal construction. I will happily use it as my main pen for years. It's also the most expensive. Note that it has a mechanical pencil. The others don't have that option. The 3-in-1 metal (the older version - 2024??) is nice, but it's not the same materials, and you can feel the difference. The color selectors are plastic, and the construction of the body is not as solid. It's still a nice pen, and I'm happy to have it, but I'd spend the extra money for the prime if I could only buy one. (I think the newest version is most if not all plastic. Know what you're buying.) The multipen is a commodity pen. All plastic. Works fine at the price point. It's using the same ink cartridges, so the only difference is how the pen itself looks and feels. If you can find it on deal, it may be cheaper than the price of the refills for the nicer models. If you're looking at the different options, I hope this is helpful!

## Questions & Answers

**Q: Does it rattle like most multi-pens do? People commented that for the 3-color pen. I am wondering if that is the case for this 3+1 pen.**
A: No

**Q: Does this have an eraser on or in it? Since this is a mechanica pencil/pen... Thanks**
A: Yeah, you can twist off the cap and there's an eraser under it, it's not too large but it's definitely larger than the eraser's in any of the alpha gel or kuru toga lines.

**Q: Does it feel comfortable on your hands when writing as the Mitsubishi Select 3&1?**
A: Yes, of course but if you have bigger fingers I doubt. I think it is personal choice ...I enjoy writing since it has colors and pencil.The best is , look in a shop selling pen and you can make decision on buying. I am glad that I have one !

**Q: I realize the pen width is 0.7mm but does it write like a fine or medium point pen?**
A: Medium

### ⭐⭐⭐⭐⭐ My Favorite Multi-Pen
*by B***L on March 16, 2017*

As someone who is addicted to writing implements (I can stop buying them any time, right?) I have to say this is, overall, the nicest multipen I've had. It seems well made. The matte finish gives a decent, non-slippery grip. Its metal construction gives it a nice mid-weight, heavier than plastic but not so heavy one would notice it much. Although a bit wider than a stick pen, I find this remarkably slim for a three ink plus pencil combo unit. It uses the standard multi-pen refill, the Type D1. The three included when you buy it are of course Jetstreams. For those not familiar with them, the Jetstream is a hybrid ballpoint; it falls somewhere between the familiar old school ballpoint pen and a gel pen. Jetstreams in particular have a fine reputation as smooth writers. These refills are excellent that way, exhibiting both the Jetstream smoothness and its good line quality, heavier and darker than most ballpoints. Of course a darker line means the ink will be used up sooner. D1 refills don't hold much ink, and Jetstream D1 refills are more expensive than most, so this may be a concern. One could use less expensive, standard ball point D1 refills from any number of other companies if expense is a worry. It is a standard refill type, so there are many brands available. As for the multi-pen itself, it is nicely made. It is mostly metal. The lower barrel rotates reasonably smoothly to switch between the various pens and pencil; not as smoothly as my Zebra Sharbo X, but that only has three units; two pens and one pencil. Didn't come with them either, you had to buy them extra. The Uni comes fully loaded and ready to go. You can change ink colors by turning the lower barrel either way. I had another pen where you could only turn it one way; once you went past blue, for example, the only way to get back to it was to continue all the way around until it came up again. You couldn't turn the pen one notch backward. It's surprising how annoying this gets after a while. Turning the barrel the "wrong way," the direction that would unscrew the barrel so that you can remove it and replace worn-out ballpoints, risks unscrewing the barrel when all you wanted to do was change ink color. However, only the lower three quarters or so of the barrel actually come off when you want to replace refills. There's about an inch wide section, the flared part just below the pen's clip, that doesn't come off. Grip this section when turning the barrel the "wrong way"and it won't unscrew on you. The pen can have a slight rattle when writing, but no worse than I have encountered in ordinary, single color, push button retractable pens. All in all a neat gadget. I like it very much.
