This A4 Sketchbook from Derwent is a hardback book containing 40 sheets of heavyweight 200gsm black paper. As it is a heavyweight paper it makes it more resilient and can take a minimum of 10 pencil layers before you\'ll observe surface deterioration. The paper works well with water soluble pencils for light washes, and using coloured pencils in general can really make your artwork pop especially against black paper as it will appear more vibrant. Derwent\'s Metallic or Coloursoft pencils will work particularly well on black paper. - Brand: Derwent - Size: A4 - Black Paper - Portrait - 200gsm heavyweight paper - 40 sheets
