Hello! I found my missing Vanishing Point today. I tried to write with it, but it looks like the ink dried out in the cartridge converter. I tried to clean it by filling the converter with water and emptying, but the pen will no longer fill this way. In fact, when I twist the converter to empty it, it sort of pops up. And when I try to fill it, nothing comes up. I see there's a small metal part that is loose--I can't remember if it's supposed to be loose or if it's supposed to stick to the part of the converter that twists up and down. Right now I'm soaking both the nib unit and the cartridge converter in some water, and hoping that does the trick. Does this just need to soak for a longer time, or does it sound like something else is wrong? I think it's weird that the converter pops up--I've never had that happen before. Also, when I tried to flush the nib unit with a bulb, it was "constipated" and the water did not go through the nib like usual. Anyone else have something similar happen, and have suggestions for making this pen be able to fill again?
