Hahnemühle Watercolour Book made of 100% cotton rag - masterful craftsmanship meets the finest cotton fibers The Hahnemühle Watercolour Book made of 100% cotton fibres is a must-have for all watercolour artists. The fibre cotton gives the paper a natural white tone, an incomparable texture and high resistance. Colors flow superbly on the natural white paper, while brushes slide gently over the surface and inspire artist. The 30 sheets of 250 gsm paper have a homogeneous, fine-grained surface structure on the front and back, so artists have 60 pages available for creative design. Suitable for all watercolour techniques, especially the wet-on-wet technique. Masking pens and masking tapes can be removed without leaving any residue. Even the use of an eraser is possible thanks to surface sizing. The pitch-black, sturdy cover with a black bookmark gives the book the elegance and stability that it needs as an indispensable companion. A rubber band closes the book tightly.Like all Hahnemühle papers, they are age-resistant, acid-free and vegan.
