Hi all I really love the feathers that lamy produces and currently my favorite pen is my 2000 lamy that makes me an extremely practical fountain pen because I can perform a deep cleaning or grease the piston without any difficulty and write perfect. Recently I just saw the lamy imporium titanium model and it looks pretty good and from here my question arises if it really is a good and reliable fountain pen? What are the pros and cons of this fountain pen? Is the body really titanium or is it a cheap metal coated with titanium ? Above all I have seen that there is a lot of controversy because despite its price it has a cartridge / converter filling system. What do you think about the lamy imporium really worth it?
