I don't know how many people know about these pencils but they are absolutely beautiful and a dream to use. You can use them dry to create strong vivid tones. then apply a light water wash to achieve a translucent, ink-like effect. Wash the pigment out completely and once dry, the color will be permanent and can be worked over again with both soluble and non-soluble media. The possibilities are endless, the results stunning. We carry single pencils as well as the sets.
