The first time that I...

The first time that I used a Uni-ball Signo RT, I was in love. I had gotten it in a random set of pens from one of my mother's co-workers who was moving to Japan. I have spent the last six years or so trying to find more of them!

Many pens will try to measure up, but I have yet to find a pen that matches combination of the smooth writing flow and the precision of the .38mm tip. I was so excited to find these pens available on JetPens! I immediately bought the 8-pack, plus two black singles, a lavender-black single, as well as a blue single. I couldn't be happier!

These pens write the best for .38 mm. Now for some of the colors are a little off from it's barrel color. So don't buy these pens based on barrel color. The colors aren't neon-ish either. I like how each color has the same color barrel! No way you can get confused there xD

April 16, 2011
My favorite pen. Smooth consistent inkflow combined with a super dense ink formula all in a pen that's light and retractable (easy to use on the fly) makes this the first pen I grab for 99% of the time. The set is great and the extra colors really makes it a must for people who are OCD when it comes to organizing.

This is the gel pen! I have tried it extensively after serenading my way through the pilots and staedtlers and pentels out there. If you crave perfection, then this is your baby. Look no further. It's smooth from the first to the very last drop.

These are like the awesomest pens in the .38 category. The colors are very vibrant and they write smoothly. they are also great for sketching if you sketch with pens
