The pen writes absolutely spotless (with blue ink directly from the same manufacturer). No leaks, no ink bleeding when you directly turns the page as described. The pen glides over the paper very pleasant.
Material is very high quality and was absolutely makelos, no scratches, or other abnormalities disturbing things. This should and can be at the filler (and the price) expect.
Therefore I would recommend to anyone looking for a good writer, advised only to this pen.
I do not regret buying ...
