The Copic Sketch Marker is a popular sketching tool for fashion designers, graphic artists and manga illustrators. These versatile, double-ended markers feature both a medium chisel tip and a super brush end that acts like a paintbrush, producing a range of strokes from fine lines to wide colour fills. The non-toxic, alcohol-based ink dries quickly, acid-free and permanent. Roll-proof flat barrels, guaranteed colour consistency, refillable ink and replaceable nibs make Copic Sketch highly economical and reliable. Conforms to ASTM D-4236.
