Mitsubishi Pencil UMNSP38.38 Gel Ballpoint Pen Uni-Ball One P 0.38 Orange

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.

This is an adorable little pen that’s gonna take some time to get used to writing with, but it’s great! I love the .5 tip, the ink color is a true black and it writes incredibly smooth. Compared to the Uni-ball Zento, I prefer the ink in this pen. The Zento is great, the ink is just not as black as the ink in this pen. It also handles the highlighter test well and barely smudges! I love it so far! 10/10!

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.

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)

The Uni-ball One P gel pen writes like a fountain pen, but has the convenience of a ball point. The 0.5 tip produces an intense color saturation and dries immediately. If you require a thinner line the 0.38 tip is a good alternative. The thicker body is easy to hold, especially for arthritic fingers and comes in an assortment of colors to suit your tastes. This pen is excellent for writing checks, memos and notes. The Uni-ball One P gel pen would be a welcome addition to any writer's desk at a very affordable price. Peter P.

Cute little pen! Nice and small but easy t9 hold and writes smoothly

Got 1 of these pens and it was so good, I immediately ordered 2 more. From the flow on ink, to fine delivery of precise writing (0.38) to the smooth writing experience, this pen is amazing. The fact that this one an award for Japan's 2024 stationary competition speaks for the product itself. I was sad to realize my pen stopped working/ink started to dry out and not write as smoothly just about a week or two after I started using it however, and was gravely disapppointed. I have 3 and the other ones are working well but hoping their quality isn't just when they are brand new and hoping they will last longer than the first one I had purchased. Would have hoped a pen like this could last months AT LEAST given the price tag. Update - after 2 months of use, I can confirm that while these pens are great brand new, they run out of ink and the flow of ink/delivery sharply drops in quality about after 2.5 weeks - 3.5 weeks after use. Quite disappointing for a pen at this price point. Not sure if faulty product or pen just has a short life. Probably better pens out there with longe lasting quality.

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 ….

Mini bolis de una calidad impresionante. Fluidez en la escritura. Pequeño y agradable al tacto. Diseño limpio y bien acabado.

Torkar ut snabbt och inte alls värd hypen. muji gör Det 100000x bättre

The Uni-ball One P is an excellent compact pen with a smooth ink flow and very comfortable grip. The ink is rich and vibrant, making writing feel clean and precise, while the small size makes it perfect for carrying every day. Despite its minimalistic design, it feels surprisingly premium and well made.

Great little pen, writes very smooth. Nice feel in the hand. But it is shorter so it might be a bit of an issue if you have larger hands or want a bulky pen. Great to have IN your pocket.

Als je niet goed meer je pen kunt vasthouden of op dun papier moet schrijven echt de pen om te gebruiken. Fantastische inkt en 0,38 mm is prima om klein mee te schrijven
