I do a great deal of design sketches in my architectural practice as well as continuous travel sketches. Mont Blanc ink is the only brand I use. Extremely good quality, does not fade or clog the pens. It also has significant water proof quality for sketching in light rain showers.

What is your opinion of the quality of this item? Not only is the ink incredibly smooth, but the colors are deep and rich. Deep rich color (the toffee brown is incredible) and very smooth. The shape of the bottle means you can use all the ink you paid for, but you won't pay too much!
