Great quality, slightly bulky

The writing experience is top-notch, typical of Mitsubishi quality. My only minor complaint is that the barrel is a bit thicker than standard pens, which might be an issue for those with very small hands.

Perfect for note-taking

I use this daily for work meetings. The grip is comfortable even during long writing sessions, and the color selection is instant. The 0.7mm line width is perfect for legibility without being too thick.

Best investment for university

As a med student, I color-code everything. This pen makes it effortless. The red is vibrant, the blue is classic, and the black is deep. Refills are also easy to find online.

No more lost caps!

Love the click mechanism. I constantly lost caps on my old multi-pens. This one is robust, the clip holds tight to my shirt pocket, and the ink dries quickly so no smudging for lefties like me.

Solid everyday carry

Very reliable pen. The clicking action feels satisfying and precise. Took off one star only because the price is a bit higher than generic brands, but you definitely get what you pay for in terms of quality.

Smoothest pen I have ever used

The Jetstream ink flows incredibly smoothly without any skipping. Having three colors in one click mechanism saves so much space in my pencil case. Highly recommend for students and professionals alike.

5 FAQ

Q: Does the clip break easily?

A: The clip is made of durable metal designed to withstand daily attachment to pockets and notebooks without breaking.

Q: Can I replace the refills when they run out?

A: Yes, this pen uses standard Mitsubishi SXR-80 series refills which are widely available separately.

Q: Is the ink water-resistant?

A: The Jetstream oil-based ink offers good resistance to fading and minor water exposure, making it suitable for important documents.

Q: Can I click two colors at the same time?

A: No, the mechanism is designed to extend only one tip at a time to prevent damage to the pen and ensure clean writing.

Q: Is the tip size 0.5mm or 0.7mm?
