The Hahnemühle Watercolour Book sketchbook is made from 100% cotton and features a landscape A4 format with 30 sheets of natural white paper (250 g/m²). This paper is made from pure cotton, is aging-resistant, acid-free, and vegan. It has a fine surface texture on both sides, making it ideal for all watercolor techniques, especially the wet-on-wet technique. Masking pens and tapes can be removed without residue, and etchings can be easily performed thanks to the surface gluing. The sketchbook has a sturdy black cover, a black ribbon bookmark, and an elastic band closure.
