Uni Jetstream Multi-Function Ballpoint Pen 4&1, Equipped with 0.5mm Lite Touch Ink (Black, Red, Blue, Green), 0.5mm Mechanical Pencil, Steel Blue, MSXE5LS05.71

If you’re like me and love color-coding notes like it’s a competitive sport, this multi-ink pen is a lifesaver. No more digging through your bag like you’re on a scavenger hunt—just click, switch, and keep writing. It’s a big win for efficiency and minimalism. Plus, having a pencil built in? Chef’s kiss. Fewer things to carry, more brainpower saved.Now, the downside: while this pen is functionally solid, it’s not exactly a fashion icon. I wish there were more fun or expressive designs—where’s the purple ink or the Kuromi version when you need it? Also, if they could somehow make the ink erasable without sacrificing color quality, I’d be completely sold.Still, for what it does, this pen is a multi-tasking champion!!

Love the weight of this pen and its feel. Ink is smooth and pencil lead is my favorite size. Nice to have another option for multi-ink pens.

I had a hard time deciding how to rate this pen because it mostly has all of the things that make the jetstream 4&1 such a great pen. That said, I am rating it at 4/5 because it's just so light and feels very unsubstantial. The other 4&1s that I have have a nice metal grip that gives it a heavy feeling and prevents fatigue while writing. This pen has a light, all-plastic body that just gives it a cheap feel. It writes well, and I haven't had problems starting the ink. It flows nicely. The pen comes with black, blue, green, and red ink and a mechanical pencil insert. One nice thing about it is that the center button allows you to advance the lead, which is something other 4&1s don't have. I just can't get over the all-plastic feel of it, but otherwise it's a good pen.

i am tempted to “marie kondo” all of my other pens—this pen is that good. perfect number of colors, excellent and smooth writing quality. i take this pen everywhere with me. it’s definitely worth the price.

Great grip. The black ink cartridge skips. The rest of the ink cartridges seem to work well, and the pencil is good. For me the Ink skipping is a deal killer. I draw a lot and when I’m drawing, I cannot have a pen that skips. AD2

I bought this for my daughter and she loves it. It writes very smoothly. Seems as durable as most pens. Great deal.

This is a great pen and it’s really fun to use. It’s got good ink flow a thin line and it really matters to me that it’s got a fun spirit, especially with the colors. I have bought multiples of this pen and my children like to use it as well.

Love it write smoothly and nice feel wish they had it in purple
