## 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: Love these pens - I frequently attend meetings in different rooms and rely on this pen's mutiple colors to help me keep track of tasks, hot action items, things to look up, and other items. The ink flows smoothly, the pencil is wonderful, and the eraser quality is great. For me, the two things that set this pen above competitor offerings are 1.) the clip is large enough to clip over a book ring and strong enough not to break under normal use. 2.) I'm left-handed and find many pens smear as I write, this one doesn't. The one thing I would change about this pen, and it's a very minor quibble, would be to smooth out the transition between the rubber grip and the metal end. This area can cause a point of heat on my finger...but again, it's a pretty minor issue for me becuase I rarely write more than a few bullet points or a quick note.
Review: My new favorite pen! Perfect for Planner, Agenda, or Calendar! - I love this pen! I can label urgent, financial, personal, medical, and work items with designated colors, and I can use the pencil for tentative meetings or appointments. The barrel is thicker (of course) than the regular version of this pen and it might be a little too thick for some people, but I can work with it. The fine point is excellent, the ink crisp and clear, and legible even when I write small. Even though there are 4 colors, the ink lasts for quite a while. I purchased mine months ago and I have yet to require refills for any of the ink. If you write more than light calendar mark-ups, you might want to consider the regular Jetstream 0.38 REFILLS: I highly recommend this pen, but be aware that the refills you order for this pen are thinner than the refills you'd order for the regular 0.38 Jetstream. This pen will not accept the larger refills. PAPER: I use this pen with my Hobonichi Techo Cousin, Weeks, and Day-Free with mild show-through and no bleeding. These products use thin Tomoe River Paper, and I LOVE THE WAY IT LOOKS! BLOBS: This is a ball-point pen with better technology, but you will occasionally have blobs of ink. I wipe the pen if the ink looks a little thick, and keep going. I'm a pen snob and have avoided ballpoint pens like the plague for a few years, but this line of pens is worth the occasional blob, IMHO. Don't try to create lines or linear drawings very much with it, as you might have more blobs than with writing letters.

## Questions & Answers

**Q: It says 4 and 1 though it lists 3 colors for ink in the description, and it does not mention black. Can someone clarify how many ink colors there are?**
A: Ink colors are red, green, blue and black.

**Q: My pen did not come with lead in the pen and the black ink is not working smoothly after a couple of hours is this normal?**
A: I totally agree with you. I was so disappointed with this pen. The writing is not smooth at all. The ink was constantly skipping. I just gave up on it.

**Q: How is this for people who write with their left hand?**
A: Works equally well for left handed and right handed writers.

**Q: What do you click to get the pencil to work? The buttons for the different ink colors are obvious but there’s nothing noting how the pencil works.**
A: The silver clip piece is the button for the pencil.
