They feature a dual-tip design: one brush tip for painterly lines and one fine tip for details. The brush tip is flexible and smooth, transitioning seamlessly from thin, medium to thick lines with the slightest pressure. The single ink reservoir ensures that colors match up. Blend colors on a palette and apply with the marker tips for and endless palette of color; tips self-clean after blending. This set includes a colorless blender for subtle gradients and effects, as well as nine colors: chartreuse, Alice blue, bright blue, tiki teal, jade green, deep magenta, poppy red, mauve and pink punch.
