Copic Sketch Marker Sets are the perfect way to begin building a marker collection. Carefully chosen colours packaged in blending pairs or complimentary tones take the guess work out of picking colours. The Copic Sketch marker's dual nib provides the artist with a revolutionary experience and unlimited possibilities. It has a super brush nib which is flexible and long lasting, acting like a paint brush, with an experience similar to using watercolour. The second nib is a medium sized broad nib with a firm chisel tip, which is great for laying down large areas of colour and precise line marking. Due to their versatility, Copic Sketch markers are often used for illustration, papercraft, brush lettering, calligraphy and colouring in. Their alcohol based non toxic ink is permanent on most surfaces, including paper, fabric, leather, plastic, wood and more. Copic Sketch Markers are also compatible with the Copic Airbrush system, can be refilled with Copic Inks and their nibs are interchangeable.
