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: Chunky little pen - I love this pen! I bought it for my boyfriend, and he loves it as well. The ink is smooth and easy to write with. He's a leftie, and it doesn't smudge terribly. I haven't experienced any issues with leakage or broken parts. There's no soft grip, and the small size is a bit of an adjustment. The clip isn't the strongest if you're trying to clip it onto something thicker than a few pages, but it's a good little pen overall. The color selection is very nice, and the grape color is accurate to the photo.
Review: Definitely buy this pen. - So far this pen is amazing. I love the loop and how small it is, so I can clip it to my work keys. So far it writes so smooth but I haven’t tried the smudge test yet.

### ⭐⭐⭐⭐⭐ An excellent pen
*by A***Y on June 2, 2026*

This is pretty much a perfect pen in my opinion. It's extremely ergonomic, even for my large hands. It's functional, especially the clip which is much sturdier than standard plastic pen clips. And it writes beautifully. It dries almost instantly, this is one of the few pens I use that almost never smears. It's just fantastic. The only downside is the high price but honestly I love this thing so much that I can't even complain about that.
