## Description

~uni-ball one P ~ It is very cute and has a fine texture and smooth writing experience that fits in your hand. A sweet and sweet shaft shape that allows you to feel soothing during your daily life. We aimed to create the perfect shape that is short but easy to hold and write on. Product Features: ■ Small and lovely, the axis design blends into your daily life. It blends in with your daily life and interior decor and occasionally accent. I want to write a word. We pursued a cute design that is easy to carry around in such situations. The shaft color name is inspired by small and cute candy, and uses the name uni-ball one P meaning the pocket. ■ Perfect shape for short yet easy writing. We aimed to create the perfect shape that is not only cute but also easy to write in your hand. The knock part is rounded to allow for easy knocking and the clips are wide/short for shorter axes. Also equipped with a metal base (stabilizer mechanism). Provides a consistent, smooth writing experience. Refill is equipped with UMR-38S/UMR-05S common to the uni-ball one series. Find your own favorite one.

Review: Good writer, good colors, good design, click, clip, everything. - This pen surprised me. It's a great writer, and the click mechanism is really pleasing. The larger button is really comfortable on your finger, perfect pressure feeling and satisfying click. The clip is also a nice design. I love the color, the extra fine point, and the metal enforced point of the pen. The two halves of the body come together smoothly, it's got a nice subtle texture. I love it!
Review: Great little pen - Love how smooth it writes. Ink flow has been great. It is a cute size but could be hard to use with larger hands. My kids love them. It looks nice and the price is great. I just wish there was an even finer point refill option.

### ⭐⭐⭐⭐⭐ Best ink pen I own
*by Ḵ***W on December 7, 2025*

0.38 pen is great for my Hobonichi Techo Weeks; thin writing is ultra fine and clear. Works well on Tamoe paper: smooth and dries relatively fast (no blotting or blowing dry as with fountain pens). Standard black ink is not streaky but is very clear. The chubby barrel relieves my hard grip as I write, and I find I can write a bit longer than with a thinner barreled pen. Soda is a nice color and helps determine ink colors I keep (red black blue). I use it daily for Techo, notes to mom, and sermon notes. Never thought a Japanese pen would make a difference in my writing but the high quality understated function and minimalist design is the best. The size fits comfortably in my small hand, the ink refill lasts me maybe a month? Since I use all 3 ink colors it depends on which ink color I’m using ….
