DescriptionSpecifications
With their Signo RT1 pen, Uni-ball unveils an innovative tip design. The tip is rounded and edgeless to reduce friction against the paper, resulting in a super-smooth writing experience. Mirroring that smoothness is the simple body consisting of a clicker with clip, and a rubber grip that blends almost seamlessly into the barrel.

The pen has a VERY fine tip which I prefer. It lays down a very thin line (hair thin), but it is dark and doesn't skip. Some rattling in the clip when writing, but I do not find it distracting. The design is sleek and it works very well.

This is a great pen. I love the look of the pen and the grip that extends to the very bottom of the pen (I tend to hold pens close to the tip). The ink flows easily and doesn't smear or smudge. The only bad thing about this pen is that the clicker rattles when pushed in. However, this isn't really noticeable unless you're shaking the pencil around a lot -- I don't notice this when writing.

This pen has now become my favorite pen. It is a thin line, but still managed to be a nice dark black, while drying fast, which I need because I am left handed. I have bought four more of these pens because of my experience with this pen.

The Uni-ball Signo RT1 UMN-155 is as innocuous as a pen can get. Once you pick it up and start writing with it, you will not want another black 0.38 pen. Consistently smooth, jet color, never skips,... amazing. Big tip of the hat to the folks at Uni-ball. They did it again.

I bought this and a Ohto Slimline retractable in the same order. One reviewer said they used to love the Signo, but now the slimline is their fave. Not the case with me. The 0.38 Signo is very smooth and balanced, while the slimline is far too slim a body (and I have pretty small hands!) The slimline is quite scratchy too which I find irritating, but otherwise writes fine. It's just not my first choice. The Uni-ball Signo is now my very first choice. A great pen all around.
