Sketch Markers are the most popular of the Copic Markers.
They are excellent for all forms of illustration, design, scrapbooks, fine art
and more. These double-ended markers have an alcohol based ink that is fast
drying, permanent, acid-free and non-toxic, and come in a vast variety of
colors. They are refillable, constructed in a unique design for a more
comfortable grip, and so they will not roll away from you. They can also be
used with the Copic Airbrush system. Durable polyester nibs come in Medium Broad
and Super Brush - a soft, flexible, fast-flowing brush for delicate or bold
expression. Sketch markers have a 3-year shelf life and are guaranteed for
color consistency. Available in over 300 colors.
