Now had 2 of these mines. Got as a gift from the university after graduation a Lamy pens, where was this mine. Have him also used diligently, after a few pages the ink but was then quickly so pale that you could not read properly. OK, thought that mine might be older. So went to a stationery store and bought a new one. Result: the same! A few sites and the mine did not work correctly. As I read in some forums, this is probably a common problem with this type and the company Lamy can do nothing apparently.
If anyone knows an alternative mine in this format, it would be nice to hear about it. The pen itself like me that is very good. Only the mine I would never buy again.
