Made from 100% sustainably recycled stone, and without any bleaches, acids, or trees, Karst Stone Paper™ is rebuilt from first principles to be better. That means more durable, more sustainable, and infinitely smoother to write, scribble, doodle or draw on. If there's a better way to make paper, we haven’t found it. Yet. | Karst | Facebook
