Great for daily note-taking
I bought a pack of these for university lectures. The 0.5mm tip provides precise lines, and the click mechanism feels sturdy. The grip is comfortable even after hours of writing.

Excellent ink, wish it came in more colors
The writing experience is top-notch. The waterproof feature saved my notes when I accidentally spilled water on my desk. Only downside is I wish the multi-color options were easier to find locally.

No more smudges!
As someone who writes quickly, smudging was always an issue. This pen's quick-dry formula completely solved that problem. The ink flow is consistent from start to finish.

Smoothest pen I've ever used
The Jetstream ink is incredibly smooth and glides across the paper without any skipping. It dries instantly, which is perfect for my left-handed writing. Highly recommend for students!

Perfect replacement for my old pens
I've been using Uni pens for years, and this model is the best yet. The refillable design is eco-friendly and cost-effective. The 0.7mm version is great for signing documents.

Solid student-grade pen
Very reliable for everyday use. The clip is strong enough to hold onto thick notebooks. It writes well on various paper types without bleeding through. A solid 4 stars.
Q: Does the 0.5mm tip feel too scratchy on rough paper?
A: Generally no. The Jetstream ink formulation reduces friction, so even the 0.5mm tip remains smooth on most standard notebook papers. However, extremely textured paper may affect smoothness slightly.
Q: Can I use SXR-6 refills in this pen?
A: No, the SXN-150/SXN-157S models are specifically designed for SXR-5 (0.5mm) and SXR-7 (0.7mm) refills. SXR-6 refills are intended for different pen bodies.
Q: Is this pen suitable for left-handed writers?
A: Absolutely. The quick-dry technology prevents smudging, which is a common issue for left-handed users. Many of our customers specifically praise this feature.
Q: Is the ink truly waterproof for archival purposes?
A: Yes, the Jetstream oil-based ink is water-resistant and holds up well against moisture, making it suitable for important documents and student notes that need longevity.
Q: How do I replace the refill?
A: Simply unscrew the barrel of the pen from the grip section, remove the old refill, insert the new SXR-5 or SXR-7 refill until it clicks into place, and screw the barrel back on.
