Pilot Fountain Pen Ink Converter (CON-40) Screw Type Value Set of 2… (2 Pack)

This converter fit the Pilot Kakuno pen which is what I wanted. It is not the biggest as you can probably tell, which I personally prefer because I can't make up my mind about ink colors and want to use all at once. So the ink gets used up more often using this converter so keep that in mind. One thing I had trouble with, I am not sure if it is because I am sort of new to fountain pens or if it was the converter itself, was filling the converter to full. I have filled others and it went smoothly, but filling this one was a little more difficult for me. It is still 5 stars because it works and it works perfectly, it is just more difficult than others to fill. Which watching a video or phoning a friend helped with the difficulty.

Works perfectly with my Pilot Fountain pen and is easy to use.

These are spectacular! I have 2 Pilot fountain pens which came with the squeeze bulb type converters but I didn't particularly like them. These are fantastic replacements. They work great, I would by more if I had other Pilot fountain pens.

Converters made it possible for me to easily fill the fountain pen with ink I chose, without having to needle syringe the ink into a spent cartridge.

Takes some repeated priming to draw a sufficient amount of ink into the converter. The rattle of the rattle of the mixing beads may irritate some. Converter msy not fill completely.
