Ideal for artistic impressions, product design, illustrations, fashion designs, sketches, calligraphy, or children's drawings. Suitable for thin precise lines, expressive brush strokes, and filling large areas. Odorless, water-soluble, quick-drying, with clear and vibrant colors based on dyes and gum arabic. Color intensity can be reduced by diluting with water or using a brush pen blending tool. The best results are achieved on lightweight drawing and watercolor paper or cardboard.
