These markers are ideal for all styles of art, design, illustration and crafts. They come in a wide range of colors, and have both a broad and fine nib tip combination with a triangular ergonomic barrel. Each marker set includes a colorless blender- a tool all on its own and not just for blending! It moistens the marker dye so it can be manipulated, helping to push the color through the paper. The ink applies smoothly and is easy to blend. These markers are permanent and free of harmful chemicals and overwhelming odors, making them a joy to use. This 8.6x7.5x.75 inch package contains 12 dual-tip markers in assorted colors and one color blender. Conforms to ASTM D 4236. Comes in a variety of colors. Each sold separately. Imported.
