In my personal experience, out of the three ink converters Pilot produces for the current line of pens, the piston CON-50 was the least satisfactory. Too often, the ink’s surface tension prevented it from reaching the feed, thus causing a lack of ink supply on the nib. Shaking the pen was the obvious solution, but there is always some risk of releasing an uncontrolled drop of ink. Needless to say, Murphy’s Law does apply here.

New, on top, and old, on bottom, CON-50 converters by Pilot.

More modern (that is, included on the 2012 catalog) CON-50 come now with a variation with respect to the older model: there is now a metallic piece inside the converter. The idea behind it is similar to that of the ball inside some ink cartridges—to break any possible ink drop on the converter or cartridge walls. The cost of this solution is a small reduction in the ink capacity: from 0.7 ml to 0.6 ml, according to my own measurements. The price of the new CON-50, however, has not changed: JPY 525 (5% tax included).

I really don't like the converters at all. Cartridges (filled with syringe) comes much more comfortable for me.

Does this design actually fix the issue?

I've always preferred the CON-20 due to it's good compromise between ease of filling and ink capacity.

Thank you both for commenting. I do agree with Write to me Often--my first choice is to refill cartridges. The second is the CON-20.

However, this metallic piece inside the CON-50 makes this converter to work a lot better.

Thanks again for passing by.
