What owners say
Well... I've been hovering around Flex nibs for a while now, even got one (from India), but was not very impressed. After your posting I have just ordered a Majohn P138 to give it another try. In a couple of weeks I'll know more about the nib and whether I'll be pleasantly surprised by it. r/fountainpens · 2 pts · thread
