Thank you for your response Baditude.
In doing some more reading, I did learn that what I have are NOT "cartimizers." I have a separate atomizer and a separate cartridge. Not sure if the cartridge is refillable or not. Don't know if I can post inks here, but I'll try. This is what my cartridges look like: 510 Cartridges
From the description:
Genuine Joye Cartridges, pre-filled or ready-to-fill.
You can refill, repack and even modify those to your heart's content. (Before I moved over to the Nova I tried the PTB mod, replacing the packing with a lipton pyramid teabag. Worked really well..)
They are really easy to refill:
Figured out pretty quick that going back to my old ways was better.
