Copic Sketch is the most popular among all the Copic markers. It comes in the widest range of colors, and features different types of nib combination. Ideal for illustration, craft and caricature.
Copic Markers are designed to last for years (or decades!) because they’re refillable, and you can replace the nibs when they become worn.
 
Vibrant, Smooth Colour: Copic ink applies smoothly and is easy to blend. The alcohol based ink dries acid free and does not destroy paper fibres the way water based inks do. Also, the open time on uncoated papers is limitless, so you can go back and re-wet the ink years later!
Permanent & Non-Toxic: Copic markers are free of harmful chemicals and overwhelming odours, making them much more enjoyable to use than other brands.
Refillable: Once you purchase a marker, it is yours for life. By simply refilling the marker and replacing damaged nibs, your marker will last a lifetime. Some artists have been using the same markers for up to 25 years.
Also “Copic Sketch Empty Marker” allows you to mix the colors or expand your collection with by using Various Ink to fill them up to 358 Colors.
3 Nib choices :  Medium Broad nib on one end and a Super Brush nib on the other. The Medium Broad tip is a firm, angled chisel that can be used to make calligraphic strokes. The Super Brush tip is a little more flexible, and feels almost like a paint brush. Sketch marker can fit an additional nib that is sold separately. The Medium Round tip is more similar to the Super Brush, albeit with a rounded tip rather than a pointed one.
