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.

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.
