I have reviewed both of these pens in the past in black ink - the Putimo here and the Pockel here. I love them both and they both have a lot to offer. But I carry enough pens around as it is, and I wanted to cut down how many mini pens were in my backpack, so I needed to decide. The first step, of course, is to order new ones of each in different colors. That's what any normal person would do when they had two perfectly good ones previously reviewed, right? RIGHT!
The next step was to compare them side by side, which is shown at left (as always, click on the image to see the larger view, and click below for the really big picture). They both write great, and in the end, the Putimo wrote a cleaner line and was more comfortable to write with than the Pockel. The only real issue with the Putimo - which is found in all Hi-Tec-C pens - is that it is sometimes a slow starter. I left the perfect example of what I am talking about on the page where I wrote "Pros". That crops up from time to time, even with the cap on, but the end result is nice enough for me to overlook it.
The Pockel is a fantastic mini pen, but the Putimo is the one for me.
