Prismacolor Premier Dual-Ended Art Markers. The dual-ended design features a fine tip on one end and a large chisel tip on the other, for a total of four different line widths with each marker. This allows you to quickly flip between precision and coverage and makes them perfect for hand lettering. The alcohol-based ink is richly saturated and designed for an effortlessly smooth, silky ink flow and offers professional artist-quality colors. Plus, they pair perfectly with the color palette of Prismacolor colored pencils for more depth and layers to your artwork.
