These pens perform similarly to paint brushes; they are ideal for drawing, coloring, customizing and lettering. Change the brush stroke thickness by altering the amount of pressure you apply while using, and the nib automatically springs back to its original shape for easy coloring. Experiment with creating unique colors with two or more pens. This set includes yellow, orange, pale orange, woody brown, dark brown, brown, vermilion, red, pink, burgundy, fuchsia, lilac, iris, purple, sky blue, peacock green, yellow green, green, sap green, fresh green, blue, light sky blue, Prussian blue and black.Details:Includes assorted colorsSet of 24 brush pensWater-based solventEasy to blendDye-based
