Premier art markers feature a brush tip on one end and a fine tip on the other, making it the perfect marker for fashion, design and hobby applications. The flexible brush tip delivers thick, thin or varied lines in one stroke. Use the fine tip for details. Labels indicate color and tip type. Advanced ink formulation provides rich color saturation and superior blendable colors. The ink is formulated to give the richest color saturation with silky smooth coverage. One ink source ensures color consistency from either end of the Prismacolor's Brush/Fine Art Marker. Nontoxic ink is alcohol, dye-based. Art markers also feature a roll-resistant cap so the marker stays put.
