I compared a green G-tech C4 .4mm with the green Uni-Ball signo 151 .38 mm. I used a cheap index card and wrote with both pens then poured two separate drops of sparkling water and let it stand for a couple of hours. After the hours past the G-Tech c4 washed out (you could still make out what was written but barley) and the lines of the index card faded away. The signo writing was STILL THERE as if I just wrote it. One thing that is different between the two is the color. One the g-tech c4 the green ink is more saturated and the signo has hints of yellow in its hue. Dont get me wrong the signo ink is very pleasant and its waterPROOF ability makes it a great pen. If waterproof ink is not important then the c4 and 151 are both nice.

These are my favorite pens. I love writing extra tiny and these are the only ones that do the job for me. Others are too inky and these are perfect.

I'm a huge fan of the tiny point and the color. The ink flows very well and writing with it is a pleasure. The design is also simple and quite pleasant.

These will most likely be my new go to pens for everything.
