Derwent Inktense water soluble pencils offer vibrant, ink-like colours that transform with water. Use them dry for intense colour, or add water with a brush to create translucent, ink-like washes. Once dry, the colours are permanent and can be layered with other media, making them ideal for mixed media art, illustration, and even fabric crafts. The pencils feature a round barrel and a thick 4mm core. Available in a wide range of 100 soluble colours and a non-soluble outliner.
