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.

Very smooth ink flow, comfortable design. In terms of writing performance, this is a very good pen. Puts down lines that seem to resemble ballpoints rather than the wetter flow of other gel pens and even the Signo UM-151 pens.

The clicker/clip tends to rattle slightly, which is a small quibble.

This pen's refill says UMR-83, meaning that it uses the same refill type and design as the Signo RT. If you're looking for a cheaper pen or refill with the same writing quality, those would also be good options.

Time will tell if the flow decreases near the end as with other gel pens, but that isn't even a complaint. None of my finer-point gel pens have survived long enough for the ink to run out completely, and I'm fine with that.

Love these pens. Love the fine line and soft grip that goes almost to the tip of the pen.

Awesome pen, awesome ink. Smooth, skip free, nice narrow line. My only complaint about these pens its that it is difficult to find the special color refills. Can't decide whether I like the retractable RT model more or this one. Both write superbly and reliably.
