This Review was preformed with a Jinhao X-750 and on a Rhodia Dot PadThis is a special ink. I have never used one with better waterproof capabilities. Usually the ink will spread, lose color, or at least show signs of having water being introduced to it. This ink showed nothing. Couple that with a decent color, and a fast dry time and you have a winner in my book. The only issue is that it seems to have a small tendency to feather. If you are scared about losing your writing, get this ink. Onto the pictures :D.
