Hahnemühle D&S line sketchbooks are strong and sturdy, tightly sewn with thread, making the page turn easy and fluid. The paper has a non-slip surface and has an exceptional abrasive characteristic, which makes it possible to create wide and wide lines easily and without much effort. The broad natural shading lends a delightful and charming hue by enhancing the subtle shades of the colors in your pencil designs. In addition to pencil, charcoal or blood drawing, D&S notebooks also support watercolour pencils. Finding your page in the D&S notebook is easy, thanks to the convenient red bookmark (please note that the "Mini D&S" sketchbook is not accompanied by a bookmark). Available in various formats: 14x14, 19.5x19.5, 25x25, 9x12.5, A3, A4, A5, and A6. Acid free, neutral ph, aging resistant and vegan.
