Ok with all these fp threads popping up, i need some suggestions. About 2-3 years ago I bought a fp, a cross century ii, I quit using it bc it leaked all the time in my pocket, so is it the ink or the converter or what? btw all i have ever used in was the private reserve velvet black ink that came with it. Thanks in advance for suggestions, bc I would really love to get some good use out of this pen.
