Scores of anime, manga and comics artists – as well as landscape, product, architecture and fashion designers – prefer Copic markers because of their ultra-blendable, low odor, alcohol based inks. Unlike water-based inks, which tend to pill and oversoak the paper while blending, Copics mix on the surface to deliver the wonderfully rich blends they're known for. This outstanding performance has distinguished Copic markers as the celebrated coloring tool within professional, semi-professional and hobby circles alike. The replaceable Super Brush nib acts like a paintbrush in both feel and application. Sketch Markers feature refillable ink and optional nibs and are compatible with the Copic Airbrush System. This set contains the following colors: YG0000, G0000, BG0000, B0000, C00, W00, BV0000, V0000, RV0000, R0000, YR0000, Y0000.
