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.

For some reason, the pink version of this pen that I ordered is much smoother than the blue version, this inconsistency bothers me, but there's no doubt that this is one of the smoothest pens I have ever had.

I usually don't write with pens that have such a fine point, but I just loved the look of it too much and had to have it. It took me a little bit of time to get used to it, but I ended up really loving it. The ink flow is smooth, and the lines are crisp and sharp -- it makes it easier to keep your handwriting neat and tiny. I'm super glad I bought a refill with it, because I've been using this pen endlessly since it arrived.
