This is a good fountain pen, but ultimately I think its a little too hard steel pen for writing. I yielded to temptation by buying and I almost regret because I use it very occasionally, preferring to write with my old pen Waterman C / F (which indeed the pen is gold).
I therefore advise the collectors only to the uniqueness of the model, first because of its high price, but megalomania seems to have reached the manufacturers of fine fountain pens, and then because I only write not as fast as with another, but that may be due to habit.
