The Prismacolor Cool Grey Marker Set is a great way to practice your shading techniques with markers. Every artist can appreciate these double-ended art markers. The ink is formulated to give the richest color saturation with silky smooth coverage. The duality of the thick and skinny tips let you change it up whenever the mood strikes. One ink source ensures color consistency from either end. It’s an alcohol, dye-based ink that’s non toxic. With 12 tones from light to dark this gives you a full dynamic range of tones to accomplish what you need.
