Looking back on the use of this ink, I realize that I really enjoyed it. What I do not mention in the review, below, is that it actually had a very nice smell, too. I have never smelled actual frankincense, but, if it smelled like this, I imagine that I might enjoy it. Please ignore the fact that I refer to it as a green ink. It is definitely a primarily grey ink.
This scan was done on an HP Deskjet F4280 at 600dpi.
Note: Because these scans are done with a light emitting printer, actual colors will, more likely than not, be slightly darker than they may appear, here. The colors shown, here, are probably a bit more reminiscent of what the ink would be like under a bright light or if it were held up and viewed with a light behind it.
