Disregard- found pen compatibility thread. 
Just received my Inka pen today, and I’m fairly pleased with it, except that the ink cartridge doesn’t write as smoothly as I prefer.
I love the way Zebra fine-point refills (such as for the 701) write. Are there any ink refills that would fit the Inka and write like the Zebra?
Sent from my phone. There are many like it, but this one is mine.
