Derwent Inktense water soluble pencils are known for their vibrant, ink-like colours. These pencils can be used dry, but truly come alive when water is added, transforming the pigment into vibrant, ink-like washes. Once dry, the colours are permanent and can be layered over without affecting previous applications. This permanence makes them suitable for various art projects, including use on fabrics like silk and cotton, as well as surfaces like ceramic and wood. The pencils feature a round barrel and a thick 4mm core. They are available in a wide range of 100 soluble colours, plus a non-soluble outliner.
