The Derwent Inktense Blocks have all the brilliance of the Inktense Pencils but in a chunky block making it easy to cover large areas really quickly. Just like the pencils you can use the blocks dry but they come into their own when you mix them with water and the colour turns into vibrant ink. Once dry the colour is permanent and you can work over the top of it. Easy to blend colours, can be mixed and layered to create an infinite range of hues and tints. Firm consistent texture produces minimal dusting. Square shape is ideal for both fine and detail and broad, expressive strokes. So versatile they can be used wet or dry, or mixed with other media. Once it's dry the colour is fixed and you can work over the top of it. Due to its permanent feature it's great for using on fabric such as silk and cotton. Supplied in a storage tin.
