Thankfully it doesn't look like cardboard when you write with it. For me, it's one of the better Montblanc inks. It took me a while to get it but now that I have it I'm very pleased with it. It's somewhat watery which may not suit some, but is a pale - but pefectly legible - sepia that's actually well named and more complex a colour than online pictures do justice.
I foolish decided to pay the 35 euros to the doctor for a Tetanus injection, so it will have to wait till next month. In the meantime, if you could get around to scanning a sample of writing, I for one would love to see it.
