Pilot CON-B Fountain Pen Converter

This is a product that is being deployed overseas as a replacement for the discontinued Pilot converter CON-20.

Due to its simple structure, it has a large capacity, and compared to CON-40’s 0.4ml, CON-B’s actual measurement is about 0.62ml, which is more than 1.5 times the capacity of CON-B.

It uses a method in which the exposed silicon sack is pushed by a leaf spring to suck up the ink.
