Draw, sketch and more in the astonishingly smooth Stone Paper Sketchbook from stationery innovators, Karst.

Unlike familiar tree-based paper, the pages of Karst's Stone Paper Sketchbook are made from a recycled calcium carbonate. The result is an incredibly smooth and bright white page for you to practice your character designs, mock up logos or just absently doodle. Because of that unique material, each page also features a resin coating that makes it both waterproof and almost impossible to tear, so if you're after a hardwearing sketchbook, you're in the right place.
