Dan Placed on 24-01-2023 I have been collecting and writing with vintage and modern fountain pens for 25 years. Aurora ink is simply in my view the finest fountain pen ink on the market. This ink has stood the test of time. As part of the path that physicians take it states “ first do no harm” and this is precisely what this in does. This and perhaps Waterman is the only ink I would put in a vintage pen. The ink is free flowing not too wet and not too dry and seems to have recuperative effects in problematic pens or finicky pens. I have had pens that I have had nibmeisters work on when the nib and feed would not flow well and the problem still persisted. Once I used Aurora in the problematic ink the problem was solved. I have also found that once a feed has been saturated with Aurora ink after several fillings the results can be extraordinary. For me the range of colors also work. The black and blue are my favorite. You simply cannot go wrong with this ink. I highly recommend.
