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.

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.

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.

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

No leaking, No smearing (i am lefthand writer) I love this pen....functions beyond my expectations.
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.
