Review: The best pen I've ever used! - This is hands down the best pen I’ve ever had. It writes incredibly smoothly, never skips, and the ink is a beautiful, rich black – deep and crisp. The fine tip gives great precision, making writing a real pleasure. I loved it so much I bought a second one and stocked up on refills (3 blue and 3 black!). It’s no surprise this pen won an award in a Japanese stationery competition – it truly deserves the praise. Highly recommended for anyone who loves a high-quality writing experience.
Review: Great! - Wonderful making; perfect ink. I bought three of them.

Wonderful making; perfect ink. I bought three of them.

### ⭐⭐⭐⭐ Gorgeous Black Ink
*by L***C on 29 January 2026*

Gorgeous deep black ink and a satisfying click, only real issue is that it’s such a smooth barrel on the pen that extended writing session can be a pain due to how tightly you have to hold the pen
