Pilot CON-40 Fountain Pen Converter

Easy to navigate website and quick response to order.

Doesn’t fill up much

This is a perfectly usable converter for Pilot fountain pens that works even in short pens like the Prera. I don't like that it's got a really short knob on the end that makes it a bit hard to turn, and I don't like that there is a "strainer" and some dead space at the end, which makes it harder to clean than other converters.
