Hi, folks. I have an odd little question. I know that Paper Mate has produced quite a few fountain pens throughout the years and my question is this - is there such a thing as an ink converter for the aforementioned brand? Specifically, is there an ink converter for the Paper Mate Berol fountain pen? I have a friend who just obtained one and is really keen to use it with ink wells and the syringe refilling system. Thanks in advance for any and all help!!! - X.
