Uni Jetstream Multi Pen 4 and 1, 0.38mm Ballpoint Pen (Black, Red, Blue, Green) and 0.5mm Mechanical Pencil, Baby Pink Body, Pink Gold (MSXE5100038.68)

I’ve purchased at least 30 of these pens—some for myself and others as gifts. I chose them specifically because of their 0.38 mm fine tip, which is perfect for writing in books, journals, and even the Bible. The ink writes smoothly and cleanly without bleeding through, making them ideal for precise and detailed notes. I also appreciate the variety of four colors plus a pencil—it’s a fantastic selection. Everyone I’ve given them to has absolutely loved them! If you’re looking for high-quality, fine-point pens that combine precision, comfort, and style, this set is an excellent choice.

I love this pen!! It’s professional, sturdy and great for bullet journaling! I’ve been a fan on this pen for years and this is my 4th purchase, they work great with refills, but I wanted a different colored pen. The rose gold is so pretty! It is heavier than a traditional ballpoint pen, but the grip makes it comfortable to write with. It wasn’t obvious, at least to me, how to use the pencil. You push the pen clip down to access the mechanical pencil, it took me a little while to figure that out initially.

Love these pens! Ink flow is very good. 5 writing utensils in 1.

I love these pens. They write very smoothly. The multiple colors are nostalgic, but also very helpful for organizing my work notes.

​As someone who loves precise, ultra-fine writing, this pen is an absolute dream! Finding a 0.38mm multi-pen that writes smoothly without scratching or skipping can be a challenge, but Uni-ball nailed it with the Jetstream 4&1. ​Silky Smooth Ink: Jetstream hybrid ink is famously incredible, and this is no exception. The black, blue, red, and green inks write instantly with crisp, dark, smudge-free lines—perfect for lefties or planners! ​Mechanical Pencil Integration: Having four ink colors plus a 0.5mm mechanical pencil and eraser all in one sleek body makes it the ultimate all-in-one tool. ​Comfort & Build: Despite holding five writing tools, the barrel doesn't feel overly bulky. The rubberized grip makes it comfortable for long note-taking sessions, and the clip feels sturdy. ​If you color-code your planner, take detailed notes, or just appreciate high-quality Japanese stationery, buy this pen immediately. It hasn't left my side since I opened it! So worth the money.

My favorite pen of all time.

Nice functional pen and pencil. I love it. I just wish I knew where to get the replacement elements.

I have this pen in the 0.5 mm ballpoint size and wanted another one in the 0.38 mm size. This smaller point size is comfortable to write with and the ink flow is steady. Apparently this particular pen has recently become popular.

Mine one’s not good. Ink doesn’t have a smooth flow

ジェットストリーム系は、ほとんど持っていますが、一番使いやすいと思います。0.28はシグノ系でないとインクが途切れます。この０．３８は絶妙なバランスです。細かい字が綺麗に書けます。たまにかすれる事がありますが、問題の無いレベルです。お値段もお手頃です。カラーバリエーションも綺麗なので好感が持てます。

別名「高市ボールペン」と話題になっていたので買いました。実際に、インクの伸びが良くて書きやすいです。

総理大臣への憧れで 購入しました。 推し活目的でしたが、今では手放せない非常に便利なペンなので毎日使ってます。 これ使うだけで仕事のモチベ上がりますね
