Question for you experts from a newbie. I have MB146 F and Waterman Expert II M. When I use them in my lab book, ink bleeds through the back side and causes inconvenience. I flip the nib to write in very fine line. Yes, it feels somewhat scrachy, but it enables me using backside. This has been my little secret..
So the question is, can I do this? Would the nib gets damaged if I keep doing it? Thank you in advance for your insights!!
