This set of Copic Ciao markers is great for anyone who wants to try out Copics without the much higher cost of the Sketch or Original series, and would also be a great gift for a teen artist. Copic markers are high-quality professional design markers, made with refillable alcohol-based ink and changeable nibs. Using varied shades and the colourless blender pen (not included in this set), you can blend them easily, and create a watercolour effect with a water brush. The twelve colours included here make a great starter set for someone who wants to begin a collection, or for someone whose colour needs are very simple.Be aware that Copic markers will bleed through any paper other than paper designed specifically for alcohol-based markers, so always work on top of scratch paper, or a surface you don't mind inking up. Additionally, Copic Ciao markers are not compatible with the Copic airbrush system.
