Good grip, nice weight
Very comfortable to hold for long writing sessions. The transparent barrel looks clean and professional. Deducting one star only because the cap can be a bit tight sometimes.

Office staple
Bought a box for our office team. Everyone loves the minimalist Japanese design and the reliability of the Uni brand. No more jammed pens during meetings.

Perfect for exam color-coding
I bought these for my university finals to color-code my notes. The ink flows incredibly smoothly without skipping, and the transparent body lets me see exactly how much ink is left. Highly recommend for students.

Great value, classic design
These pens remind me of the ones I used in school years ago but with better ink quality. The 0.7mm tip is perfect for everyday writing. Only wish they came in a larger pack.

Best budget pen available
You get premium Japanese quality at a very affordable price. The colors are vibrant, especially the red and blue. Will definitely purchase again.

Smoothest oil-based ink ever
The atomic ink formula is no joke. It writes effortlessly on various paper types without bleeding through. The multi-color feature saves so much space in my pencil case.
Q: Can I use this for left-handed writing?
A: Yes, the quick-drying oil-based ink formula is excellent for left-handed writers as it minimizes smudging.
Q: Is the ink waterproof?
A: The oil-based atomic ink is water-resistant and smear-proof once dry, making it suitable for important documents and exams.
Q: Does this pen come with refills included?
A: This specific model is typically sold as a complete pen unit. Refills are available separately under compatible Uni refill codes.
Q: What is the exact length of the pen?
A: The pen measures approximately 14.5 cm in length when capped, offering a balanced feel for most hand sizes.
Q: Are the colors interchangeable in one pen body?
A: No, the SA-S Classic is a single-color per unit pen. However, you can purchase a set containing different ink colors.
