Every artist can appreciate these double-ended art markers! They can create up to 4 different line styles and are fun to use. One end has a chisel tip and the other features a small nib. The small nib of the Prismacolor Premier Double-Ended Artist Marker Sets allow for relatively fast and spontaneous art, with a juicy ink flow. The chisel tip can create up to 3 different styles, including a thick, bold line for shading. The ink is formulated to give the richest color saturation with silky smooth coverage. One non-toxic, alcohol dye-based ink source ensures color consistency from either end. The ink also has minimal odor, which makes it ideal for prolonged use with large works of art.
