  Love these Uni Ball Signos...., December 5, 2013
Love these Uni Ball Signos. They are chemically resistant and work well in challenging (earth) environments.
  The Signo UM-151 has..., June 16, 2012
The Signo UM-151 has quickly become my everyday, go-to pen. The ink flows incredibly smooth, there is no scratchiness, and the ink dries quickly with no bleed on every paper I have used so far. I chose the 0.5mm simply because I had some experience with a store-bought Signo in the 0.38mm size, and I found it a little scratchy for my taste. Obviously, this is a personal choice. I know that many of the reviewers here love the ultra-fineness of the 0.38mm.

I will tell you that the 0.5mm in this pen is unlike any 0.5mm I have used that was purchased from a store in the US. This pen produces a finer line without the scratchiness I usually associate with a fine, metal point. The grip is very comfortable, and this pen has been a joy to write with, even when taking copious notes as I do with my job.

When it comes to color, I have to admit, I love this orange. Is it the most professional color, no. However, I'm not handing my notes into my boss to be graded. I use this color in combination with two others to color code my notes. Also use this to underline and highlight material. Fantastic, bright, yet deep, orange color.

I will definitely be ordering more of these, as I anticipate using them often.
