Equipped with quick-drying Jetstream ink, it delivers smooth, smudge-free writing ideal for professionals who demand precision and versatility in a single, refillable tool.

## Description

New lineup with a ball diameter 0.38mm has been added to the popular "Jetstream 4&1" Series. A ball diameter 0.38 mm is suitable for writing small letters, writing on a small space such as a notebook or memo pad. Since the ink is equipped with "Jetstream ink", It can be drawn clearly and darkly, and it is also excellent in quick drying.

Review: The Best Pens! - Uni Jetstream pens are high quality. They write smooth thin lines (0.38). I have been using them for over 10 years and will continue to do so. I love the multi-colors. Perfect for those who need to take notes, using different colors. They look professional. Pen refills are readily available. Strongly recommended.
Review: Excellent precision writing tools - I used to carry some really nice custom made pens loaded with Jetstream refills (0.5mm) until I met these 0.35mm Multi Pens. An engineer I work with recently returned from Japan where he always buys a few to bring home. He was eyeballing one of my custom pens and I was eyeballing his multi pen. We traded. I've been hooked ever since. It is so nice being able to write color coded field notes, redline schematics, and pencil mark practically anything all with one well-made pen. I write very small so finding a pen that can draw such a consistent thin line without bleeding all over the page or smearing is a rare find. I've found nothing that works better. I highly, highly recommend these pens.

## Questions & Answers

**Q: Is this ink waterproof?**
A: Practically all Ball Point pen ink is water proof, for accidental liquids.  If you blot it up expeditiously, you should be fine.  If your plan is to soak the paper in water to test the ink, well good luck.  If you want to take notes during your scuba class find a different instrument.

**Q: Where can you find replacement erasers for this?**
A: You should look for it on Amazon with the keyword "Jetstream replacement ink or eraser".

**Q: Where can you get refills for this? I can find 0.5mm, but not the 0.38mm.**
A: Here's a link on Amazon.

**Q: How do you get the lead to come out?**
A: The metal  "clip" (for lack of a better word) is actually for the pencil lead. I found that out by accident.
