So I borrowed a friend's Picasso (#901) fountain pen this weekend to test out. They're cheap and some of their models have interesting designs. The Picasso seemed to write nice, but I decided it was a bit too thin and light for me. In checking out other Chinese pens, I came across the Kaigelu which appears to be slightly thicker, longer and heavier than the Picasso. The reviews I was able to find were good, except for a couple of screw top and ink flow complaints. Has anyone here purchased or tried one of these pens recently? Are they undervalued or overpriced?
