Smoothest pen I've ever used
The ink flows incredibly smoothly without any skipping. The quick-dry feature is a lifesaver for my left-handed note-taking; no more smudges!

Reliable daily driver
I go through pens quickly at work, but these last longer because the ink efficiency is excellent. The press mechanism feels very sturdy.

Good value for money
Solid construction and consistent ink flow. It writes well on various paper types. Took off one star just because the clip is a bit tight.

No more smearing
I write fast and usually ruin my pages with smears. This pen dries almost instantly upon contact with paper. A game changer for my journaling.

Great quality, limited colors are nice
The writing experience is top-notch as expected from Uni. The limited color body looks unique. Only wish the grip was slightly softer.

Perfect for students
Bought these for my college exams. The waterproof ink means my notes stay safe even if I spill water on my desk. Highly recommended.
