This product is only sold fully customized. This means that you can and must choose your own design (colour, logo, text etc.). This Rockbook provides a loving and sustainable home for your most inspired scribbles, your biggest life goals, and of course, your most mundane to-do lists. The foundation of this Rockbook consists of recycled stone rubble, which not only saves the pulp of life-giving trees, but also water, bleach, nasty toxins and CO2-emissions. And ironically, this grainy heritage results in the smoothest writing surface. Trust us, we’re biased. Rockbooks are for anyone who wants to change the world with the stroke of a pen.Ruled notebookDimensions: 14,8×21 cm80 sheets made from stone paperSuper white paper, but no bleach or nasty toxins used at allColored cover printed with ink based on vegetable oilsWaterproofAlmost impossible to tearSmooth writing surfaceElastic closureCover made from 300gr cardboard and stone paperDivider ribbonPlease note that the ink of fountain pens takes a while to dry on stone paper
