Jetstream 4 + 1

I love having multiple colors and a pencil to use in a color of my choosing. It's great that I can buy so many different colored inks. The wide pen in comfortable to hold and use, and the individual pen gliders slide smoothly. However, the ink itself could use some more lubricant; sometimes the ball gets stuck and I get a dry imprint streak (or worse, a tear on a page of my lab book) on my paper instead of inked writing.

I really like the pen. I only wish I got a .7 mm. No issue.

LOVE this pen, the convenience of having multiple colors in one pen. The writing is smooth, effortless and doesn't skip. By far my favorite pen (even beats my Mont Blanc O_O) hihihi

Best multi-pen I've ever had overall. Ink writes exceptionally smoothly and the construction is solid. You cant beat the convenience of having 4 different inks plus a pencil, and a small eraser to boot! The red body is gorgeous and this is the first (and so far only) store I've found that carries them. An absolute must buy if you want a writing utensil that not only offers multiple colors (+pencil), but also very smooth writing!

Great pen. The inks are very nice and write smoothly. Love the pencil, but wish it was 0.7mm. Difficult to keep my friends from walking off with it. Cannot wait till the white is in stock, as my wife wants one badly. Highly recommended.
