Sailor Fountain Pen Converter for Slim Model

I agree with the previous poster. I ordered one and have found that i cant use it for the sailor slim fountain pen i own because there is not a good fit between the converter and the pen nib. Very sad. Guess i will resort to what most of the other people are doing and reuse the one that is currently in the pen.

This thing holds very little ink. Furthermore, it makes a weak connection to the pen causing a leakage in between the converter and the pen. Because of the not-so-tight connection, I dipped the converter itself in a bottle of ink, and lifted the piston-fill mechanism. It filled about a quarter of the way, I then inverted it then attached it to the pen. If anyone has any advice on how to use this thing, please post. Otherwise, I'd stick to refilling the cartridge that came with the Sailor Recruit using a needle+syringe that you can buy for 35 cents at your local drugstore.
