Pilot CON-40 Fountain Pen Twist Converter
The CON-40 fits all of Pilot's current fountain pens, including the popular Metropolitan and Kakuno. Holds approximately 0.6 ml of ink.
One customer's too little is another's just right. I'm working my way through many ink samples so this small capacity converter is perfect for trying them out without commiting to more ink. I agree with G's review that it's not the best for every day carry or frequent writer.
I bought it for my Pilot Metropolitan. It appeared this converter carries less ink than the squeeze converter the pen comes with. I don't think it was worth purchasing this converter.
However, my order was on time and there was a pleasant hand-written "Thank you!" message on my receipt.
