Daniel Smith Walnut Drawing Ink is a finely pigmented rich sepia colored water-based ink. It's great for all kinds of drawings and works well with a brush or dip pen. In washes, Damiel Smith Walnut Ink handles like a watercolor, with good layering and lifting capabilities. The rich color resembles traditional walnut-based inks, but will not fade. The warm character of walnut ink is reminiscent of drawings by Rembrandt.
