Waterproof & Tear-Resistant

Calcium carbonate is one of the principal bases of superhydrophobic coatings. Which is a fancier way of saying that Karst paper is completely waterproof. So your morning coffee can’t ruin your eureka moment, and the rain can’t steal your thunder.

Recyclable & Tree-Free

Stone paper holds a C2C Cradle to Cradle Silver Certification. That means if you do have to dispose of your Karst notebook, have no fear; they are recyclable.

Friction-Free Writing

Stone paper is unlike anything you’ve ever written on. Completely friction-free, pens glide across pages because there is no grain direction, and ink never bleeds through. The result is a truly pleasurable writing experience.

60% Lower Carbon Footprint

Karst paper is made without cutting, transporting, or pulping trees, saving on energy and thousands of gallons of water usage, and making Karst paper’s carbon footprint 60% smaller for the same amount of wood-pulp paper.

Impact Facts

In addition to the environmental benefits of stone paper, Karst is B Corp Certified, has partnered with the One Tree Planted Foundation and is 100% Carbon Neutral.
