brand very nice, their French support helped me find mine compatible with my pen.
I was using up the pen that, but I had a nice ballpoint pen which I wanted to give a second life.
the original mine from my pen was really bad, really hard, that of schneider are as flexible as the bic.
more beautiful than a disposable pen, economical, practical and pleasant a fountain pen is ideal mines, it'll just find the pen that comes with it!
