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 made to our specifications by one of the best paper mills in Europe and is suitable for a wide range of colouring applications, including pencil, crayon, pastel, felt marker, gouache, etc. Also water colours and liquid inks can be used. Our first-rate paper has a long life and coloured sheets can be framed and displayed without the risk of rapid deterioration.
