I had issues getting this one photographed, Ill revisit when i have some sunlight to get a better one, the first pic is showing the white paper, but i had to monkey with the photo to get the ink colour to show up properly. This is a purple blue, that is more on the purple side for me, and once dried is a medium saturation level that I usually prefer
the water test had me watch a lot of ink come up but at the end i can still clearly read what i had written as it had bonded well to the paper.
The ink writes great, and the bottle is really nice with its low stance and really wide mouth, the inner fill tube to help with low ink levels as really a great detail to help out. But there was a problem with the bottle, When i put my Danitrio into it, the ink was not high enough up to catch the breather tube, a completely full bottle because of its wide stance didnt allow the nib to completely submerge to suck up the ink. The dani is a larger sized nib, and this wouldnt have been an issue with most of my pens, maybe none of the other ones, but if all you have are larger sized nibs then this bottle may be a problem for you
