A finely shaped fountain pen. Writes fine and the nib looks great. The cap can be placed on the back (if you are one of those people...). The spring agitator should not be removed. Maybe replace it with a ball bering. The only real disadvantage I see so far is that the step (where cap sits when the pen is closed) might get on your nerves while writing. Other than that I'm looking forward to the first opportunity to actually use this pen.
I ordered 2 pieces. Black and red. Write well, the red feather seems thicker and softer, black writes thinner and then not immediately write the beginning. I had to shamanize a little, and scratch in one direction, i suspect that one wing is slightly longer at the pen. Quite massive copies. Approximately like aaa batteries (little fingers).
