Uni-ball Signo DX
I am not a big fan of capped pens, but the DX just writes so well I can't seem to part with it. I bought one after reading a review off Pen Addict (one of my top 5 blogs). Liking a very fine line, I went with the 0.38 mm in black to start. Since I've got a hand-full of colors and have tired out the 0.28 mm but, have found some ink "flow" inconsistencies.
The pen rests in my hand quite comfortably. The grip is unobtrusive and after some time of writing blends into my hand. It is dimpled giving it a subtle texture and is not of a spongy rubber but hugs the pen tight.
The pen comes in a whole assortment of colors and tip sizes...
a link to the infamous JetPens will allow you to view the splendor...I trend towards the earthy colors but, the Lavender - Black is my absolute favorite. It is dark enough to use at work but, the purple keeps it an individual. I'm quirky like that.
The only think I would change about the way the pen is set up is to extend the grip down that last 1/4 inch or so to meet up with the metal tip.
Overall, this pen goes with me everyday to work in all the colors above. I would recommend it to anyone and the fact that it comes in a 0.5 mm is great for those who prefer a little thicker (normal) pen line. I use it religiously in my Chronodex, a creation of Mr. Patrick Ng. This is also my go to pen when I can not or will not carry my Lamy Safari.
