Knowing the pitfalls of Noodlers flex pens ahead of time, I just could not stay away and ordered a Konrad. Reviewing the Goulet website I came to realize that there are at least three variations (not color schemes) of these pens. There are the slimmer, shorter, cheaper resin bodied pens, the nicer acrylic pens and the less often encountered ebonite bodied pens. I was wondering if anyone had used all three versions and if they thought one was significantly better than the others. I did not realize until after I placed my order that I had ordered one of the resin pens, which has yet to arrive.
