The Uniball Signo DX, a Japanese gel ink pen in .28, .38, and .5, writes smoothly to create bold colorful strokes. This pen also happens to be my absolute favorite Japanese gel pen. I have been using the bordeaux-black and brown-black regularly since 2000. I find the tips to be stronger than most gel pens, which is important to 'heavy-writers' like myself. Please see details below regarding the recently discontinued colors. Some of these are still available on our shop as a last chance opportunity!

I love it. It writes nice and is very colorful.

Bought this in a 0.5 golden yellow. Comes across a tad orange, but I'm guessing it would have to in order to be seen well enough. Its smooth glide across paper and me being able to clearly make out the color makes this a purchase I'm quite satisfied with.

I originally got the maroon .38mm in one of the starter pen packs, and quickly fell in love. I love smooth pens that don't smudge and have a fine, distinct line, and this is it. I love all the variety of colors, and my college notes are more concise now. I went on to buy red, black, and emerald in .38mm, and lilac in .28mm. I loved the .38mm and almost used the black one all up, but I found the .28mm would occasionally struggle with dryness and would quit in the middle of continuously writing. This didn't happen with the .38mm, so I'll be sticking with them from now on, since they still have a fine tip but never quit on me.

It's difficult to give an opinion about the PRUSSIAN BLUE because I don't seem to find it much different than the BLUE. I've discovered that I'm not a big fan of the 0.38; although, I will use this size if the color is deep enough to provide good contrast, as I find with the GREEN BLACK, BLUE, BLACK BLUE, BLACK, AND BORDEAUX BLACK. Also, I highly recommend (for an alternative to the PRUSSIAN BLUE) the Zebra Sarasa Vintage BLUE GRAY. With this being said, if you like blue ink and a fan of the Signo DX line in a 0.38 tip, then you'll like
the PRUSSIAN BLUE.

My review of the 0.5 PINK is based in part on how well I can see the writing against white/ivory colored paper. I find I need a higher level of contrast to see writing optimally. While I suspected the pink might be too light for my liking, I had hoped the larger tip size would make a difference. Sadly, it did not. I also purchased the 0.38 PRUSSIAN BLUE. I was hoping for more of a difference between this particular color and the BLUE. At first glance, I could not differentiate between the two. After staring for a moment, I could see that the PRUSSIAN BLUE was similar to a denim blue and found the BLUE the brighter of the two. Still, not enough of a difference for me.
