Mitsubishi Pencil UMNSP38 13 Gel Ballpoint Pen Uni-Ball One P 0 38 Momo

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! Read more

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. Read more

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 …. Read more

TL;DWR. The pen writes fantastically and has great ink, the body is above average in build quality and ergonomically very comfortable. However the spring isn't changeable and for me was squeaky right off the bat. The Uni-Ball One P is an interesting little pen with it's stocky design. The overall build quality is quite nice and It's no heavier or lighter than most pens; I found it quite comfortable to hold even with larger hands. The plastic body itself feels fairly premium? Definitely not cheap feeling but also not completely outstanding, with the walls of the pen being just a tad too thin for it's extra circumference, leading the barrel to have some "hollowness" to it. Which overall makes it feel less dense than you think it would. However the thicker body means it doesn't need any sort of grip or rubber to hold very comfortably. The click of the pen feels disappointingly soft and the spring is quite squeaky (more on the spring later) but the actual writing experience is very nice and the ink is incredible, outperforming my previous favorite ink from Energel. It's incredibly dark, very smooth flow and very very quick to dry (like seriously the only way I could get it to smear was inking a circle in completely and then very quickly running my finger across). The pen clip being made of metal and separate from the pen body is also very nice, it means you don't have to worry about a plastic piece that can break off as the metal would bend before it would break. Now about that spring... Well it's hidden, and not removable from what I can tell, and the same goes for the push button/thrust device. Which comes with both a pro and a con, the pro being you can't lose anything when opening the pen to change ink. The con being you can't replace the spring, period. Which I could actually see being a great thing if you're giving this to a kid who likes taking stuff apart. But if you're like me and want to be able to change the spring it's pretty unfortunate. Especially since it doesn't sound all that great out of the box, though it might be smoothed out with a little mechanical keyboard lube. Again, overall a great little pen. Very aesthetic appearance wise and also comfortable to hold. With the ink being the true hidden gem of this pen. (But I gotta dock a star for the squeaky spring) Read more

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. Read more

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. Read more

I love how it looks and I love the drag of the pen when writing, it feels vaguely like a fountain pen. However, since day 1 I had issues with it skipping and not wanting to write. It's every few words, so definitely frustrating and if I have a lot to write I know not to use this anymore. I hoped with age it might be smoother but I've had it over a year, using fairy frequently at times, and keep having the same issues. It's super cute though! I love the size, it fits nice in a pocket, and it writes well when it works so I'm still keeping it for small tasks. Read more

These pens are amazing! They feel great although I wish they came in a full size option. The ink foe is perfect and all the color options are great! Read more
