Featured in our January Premium box Derwent Inktense Blocks bring a new sense of freedom to the drawing and painting experience. They are water soluble ink blocks that can be used dry or wet. Dry, they deliver pure, vibrant color. When wet, they create an ink-like paint that can be worked over when dry. Their large shape makes them extremely versatile. Use them dry to apply fine lines or broad strokes directly to the paper. Wet, they can be used like pans of paint, dipped in water to apply color directly to the paper, or applied to wet paper for instant, intense color.
