For my fountain pens, you can use pre-filled cartridges, or if you would like to use bottled ink, you will require a converter pump.  All of my fountain pens come with a standard converter pump.  However, if you would like to buy another or upgrade to a premium converter pump, you can purchase them here.


Standard Converter Pump
$2 each
 

Premium Converter Pump  (may be gold plated or silver plated)
$5 each
