Ink Review: DeAtramentis Black Blue Ink

Here I review an ink by DeAtramentis, by the title of "Black-Blue" (a pretty dark blue with hints of green). Here-in may be found my own thoughts and opinions on the matter, as well as some test results I have for (among other factors) water-resistance on Clairefontaine, Rhodia, Copier Paper, Mead Notebook Paper, Tomoe River Paper, and Moleskine papers, and using both a Hero 616 with a Fine/Extra-Fine nib, and a JinHao with a fairly-wet-fairly-broad nib as a pen for these tests/experiments.
