These water-soluble blocks combine the versatility of Inktense pencils and the freedom of blocks, opening up an exciting world of endless possibilities. Perfect for covering large areas and creating free and expressive marks, easy to blend colours, can be mixed and layered to create an infinite range of hues and tints.. Add water to create a pure, translucent, ink-like effect. Once dry Inktense becomes permanent so you can work over the top of it, and it's great for using on silk or cotton. Firm consistent texture produces minimal dusting, the square shape is ideal for both fine and detail and broad, expressive strokes. Can be used with the Derwent Grate 'n' Shake to dissolve pigments in water for more effects.
