Derwent Inktense Ink Blocks, 36 Count (2301979) VERSATILE & VIBRANT  The 8mm square block combines versatility with vivid colour. Use the edge for fine details or the side to cover large surface areas quickly. Contains full range of 36 colours. WATER SOLUBLE  Expand your creative possibilities. When blocks are used dry, they deliver pure, vibrant colour. For different effects, use a wet brush to lift colour directly from the block. PERMANENT COLOUR  Pigments dry quickly and permanently when washed out, minimizing colour bleeding. Once dry, colours can be placed next to each other or layered, without fear of colour bleeding. SURFACE VARIETY  Switch up your artistic canvas. As the colour dries permanently, its great on fabrics such as silk or cotton. Can also easily be used on paper. Modify the use to fit your project. COLOUR CREATION  Integrated palette is great for creating colours. Make blends by mixing colours together or obtain lighter shades of one colour by adding water. Mix to create a unique work of art. ACCESSORIES  For best results, combine with other Derwent products, such as Derwent Waterbrush Set, Derwent Inktense Block Spritzer and Derwent Inktense Block Grate and Shake.
