Faber Castells Albrecht Durer Watercolor Pencils are highly versatile with the ability to draw, shade and paint. They have 3.8 mm thick, break-resistant leads that are fully water-soluble, and provide sharp fine lines. The vibrant colors are easily blended when wet and become permanent when dry. On some paper, the pigment will dissolve completely and react as traditional watercolor does. Dip the pencil tip into water and draw for unique lines. This set includes 36 colors packaged in a studio box with a flip-top lid. Made in Germany.
