Jetstream 4+1 looks good, writes smoothly; would've liked softer grip, but it's fine
I thought these were 4 in 1, and some were black, blue, red, green, and some were black, blue, red, pencil. But turns out, they're 4 + 1, they have 4 pen colors, plus a pencil. Or at least this one is, which was a nice surprise. I like the barrel color, the 4 colors are all smooth like I'd expect from Jetstream, and the pencil is fine. Not sure how to refill it yet. Barrel is rubberized at the grip, but not soft. I used to have multiple pens at my desk, but any time I leave the desk, I only bring one. Got this so I could have all 4 options away from the desk. Not that cheap, but worth it for my use case. Also like that it's unlikely for somebody to take it on accident

Perfect pen pencil combo
Best pen and pencil combo. The pen glide is perfect, it has 4 colors and pencil with eraser. It is easy to hold with a good grip but doesn’t hurt your hand. Definitely recommend. I watch this pen like a hawk around others because they like it so much. Be warned, if you buy, people may want to take it. It’s so good. So functional and easy to use.

Love this pen!
Smooth to write with, and is refillable. I really like thick pens it’s more ergonomic for me.

Fabulous All In One Pen(cil)
Hands down my favorite pen/pencil. I originally saw this on Jet Pens and had to try it out. This one comes with a slighter thicker pen which is perfect for my work. I'm particular about my notes and having the option of different inks and knowing the pen is quality is amazing. At first the larger barrel was a bit awkward but you get used to it and it feels like second nature to use. Definitely a good price for the function and quality of ink and lead. Only thing I wish it had was a highlighter instead of the little eraser.

Decent for a pen that offers 4 in 1 plus 0.7mm lead!
Overall a decent pen. I bought it for the multi-color plus added 0.7mm lead which is pretty unique. Compared to the single ballpoint (Jetstream RT), it wasn't as smooth and it occasionally has spotty ink flow and you'll have to scribble to get the ink back. However, it's still a pen I would carry around in my work environment. I was unsure on how to refill the lead but a quick YouTube video got the assist. Make sure you don't load it with more than 3-4 sticks or it will jam.

The best in this category
This pen is well engineered and manufactured. I have used these kinds of pens for years and have owned many of them. This is clearly the best in all respects. It is the individual color slider type, as opposed to the twist type,i.e., Paper Mate PhD and Cross (both excellent writing instruments). The Jetstream has 4 different color ball point pens, and a pencil which is operated by the clip. This design makes changing colors much easier and can be done with the pen in hand, not so with the twist (at least for me). The pen tips are very smooth, with high quality ink. The pen is light weight but has a solid feel to it. The grip is either rubber or silicon, has a firm, comfortable feel. The eraser cap stays on, just remember where you put it. An excellent eraser, by the way, quick and clean. I have a busy, cluttered desk (student and teacher paperwork) and when I want to go from red to black to pencil, I don't want to be looking around or picking up things to find a pencil or pen. It's in my hand! And an excellent price for the quality. I think it will stand the test of time and use. I'll let you know.

Best Multi Color Pens with pencil
The writing is very smooth.The pen is very well made and it even has a pencil and an eraser. I tried several other multicolored pens and nothing works as well as these ones. Leave it to the Japanese to make such a fine quality instrument!

Ink is enough to last six to eight months of daily use.
I love this pen. I have bought these for the last 8 years. They work great. Smooth writing. The bottom tends to unscrew from the top of you carry it in your pants pocket. My careful.

I've ordered the multi with the pencil as I've been using the three colour version that comes free when ordered through the hobonichi store online. These pens write really well, plus you can use highlighters over the ink with no smudging. It is a chunkier pen however this is a positive for me as I find slimmer pens uncomfortable to grip for any length of time. Excellent quality for the price as well. Edited after the multi arrived. The pen is a little chunkier and weightier than the three colour version, to me this is a good thing as it makes the pen easier to write with. Also the 0.7 refills are even smoother than the 0.5 to write with. If I could give this a six star rating, I would especially as it's so convenient to have all essential writing implements within a single pen. It also coordinates the very nicely with my hobonichi cover.

This pen is absolutely incredible, the writing experience is comparable to using a hot knife through butter. It is so smooth and pleasant I will for sure order some more. The delivery took a while but it was well worth it.
