PEPIN® Artists’ Colouring Books contain 16 sheets of superior acid-free drawing paper, printed with exceptional designs in very light lines. The printing is done in such a way that, depending on the techniques used, the original outline will be hardly visible after colouring. The 180 gsm drawing paper is suitable for a wide range of colouring applications: pencil, crayon, pastel, felt-tip pen, gouache, watercolour, ink, and more. Coloured sheets can be framed and displayed without the risk of rapid deterioration.
