I write a great deal at work and often need to write really small. I was nervous about the size .38 because I’ve never gone below a .5. I love these pens! They are the perfect size for what I do. The color is beautiful and shows up really well when scanning or copying documents (which is another thing I do a lot of at work.) They write as smooth as any other gel pen and don’t snag the paper. My only complaint would be that 2 pens out of the box (I haven’t gone through them all yet), dry up or get clogged so I had to through them away. Still a good pen for my purposes.

Para mi es el mejor en su clase. El color azul-negro es excelente, la punta de .38mm es ultra fina para escribir letras pequeñas o escribir en letra manuscrita en renglones delgados.

The UM-151 is a pretty well-known pen so there's not much left to say about it. I've been using these for the past seven years and the only issue I've ever had was that they will stop working if dropped on the head. The only factor is price and shipping and those were both good.

Favorite pen to use. I can write very small letters and still see the clarity. Each pen is long-lasting with smooth and bold colors that don't fade over time. Also useful for writing kanji and other detailed characters, which is why these are popular where they are manufactured (in Japan). If your handwriting is of the larger size variety, you might want to avoid. Otherwise excellent for calligraphy, small and cursive writing, fast writers and quick note-taking.
