I have a con-70 that came with my Namiki Bamboo. It's nice that it has a larger capacity (0.7ml) than most converters. However I'm not a fan of the pump mechanism that blows some ink back into the bottle, and also can sometimes spray / create bubbles.
It works fine, but can anyone suggest an alternative converter, that has a conventional screw mechanism that will fit the Bamboo? I beleive the CON-70 fits the Pilot Custom. I don't need the 0.7 ml capacity, given the little writing I do at work.
