Hello Everyone, So the reason I have made it here is that I am seeking information. My brother had a Yafa Scenario Gift Set that he was not using. I traded some donuts for the fountain pen of the set and have been loving it ever since. I discovered the proper cartridges are the standard long size. But I am looking for a cartridge converter of some kind in a effort to wean off of cartridges. Anyone have any info? http://bit.ly/1u6fLRx - Yafa Link I can snap pics if needed.
