This ink is very interesting. It will make your pens write like a dream. It goes on nice and smooth, and doesn't feather, no matter how junky your paper is. It's light proof, as well as waterproof. If you want something to withstand anything you throw at it, this is the ink. It cleans off very easily with water, but does tend to leave a residue that can just be wiped off. It does have a unique smell, but if you've used any acrylic paints, it's 1/100 of that smell. It's pricey, but for those who demand it, there are no substitutes.
