Hello all, I recently acquired a Danitrio Takumi (lovely EEF nib!) with an included Danitrio catridge convertor. So far, so good. Problem is, I've discovered that ink tends to leak out of the convertor into the barrel every time I use the pen. I'm pretty sure I've inserted the convertor in correctly---it doesn't fall out and doesn't feel loose (though it does move if I try to spin/screw it)----so I'm at a loss as to what could be the problem. There are no cracks or holes in the convertor as far as I can tell. Anyways, I switched to a different Danitrio convertor yesterday (and changed the ink) and set the pen on my desk, horizontally, overnight. This morning I took the pen downstairs in my pocket, unscrewed the barrel to check the inside and saw ink on the outside of the convertor again! I'm going to try regular ink cartridges next and barring that, maybe use the whole pen as an eyedropper (since the threads are so ink-tight that none of the leaked ink ever escapes the barrel). In the meantime, does anyone have any clue what I could be doing wrong?
