## 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: Best ink pen I own - 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 ….
Review: Great pen. Love the size and colors!! With an awesome clip!! - I am a big fan of writing supplies and a .38mm pen!! So I saw this and thought why not?! I don’t usually like gel pens but this is great! Smooth writing and doesn’t glide using just the right pressure. The texture and feel make it an easy grip. Love the pastel colors and price… can’t beat it!! Oh and LoVe ❤️ the clip!! It’s great to fidget with.

### ⭐⭐⭐⭐⭐ Best pen ever!!
*by D***S on November 7, 2025*

I lost the first one so I bought a second one because I loved the first one so much. This pen comes in a zillion different colors, writes so smooth. All you have to do is look at the reviews. This pen is awesome. And I carry a very small purse so this pen fits perfect. I love it. Oh and its very comfortable in your hand even though its small.
