Hello Everyone, I wanted to ask you all about the issues i am having with Montblanc Inks for few years now. At multiple instances i have noticed that while using MB inks, even though I clean the pen regularly, the flow of ink reduces after using for 2 months and then stop causing clogging in the pen (of course with cleaning in between). I then had to go to local pen shop and get it cleaned. These inks were bought from various MB boutiques as well as authorized pen shops. These inks were not expired. Pens it has caused issue - Jinhao X450- Parker - Sheaffer Prelude - Montegrappa Fortuna Inks used Mont Blanc Toffee Brown Mont Blanc Winter glow Mont Blanc Black Mont Blanc Blue Black I am not sure if I am doing something wrong or if these inks tend to clog the pen after some time of usage. Please help !!!
