What Karst Stone Paper does

Karst Stone Paper is a Sydney-headquartered, privately-held designer and direct-to-consumer seller of stationery products made from stone paper — paper produced from calcium carbonate sourced from recycled mining and construction industry waste rather than wood pulp. The proprietary manufacturing process uses no trees, water, chlorine, acids, or bleaches, runs in part on solar energy, and yields a carbon footprint stated as 60% smaller than that of traditional paper; the resulting sheet is waterproof, tear-resistant, acid-free, and bright white. The company sells the substrate as a portfolio of branded and artist-collaboration products spanning hardcover and softcover notebooks, planners and wall calendars, action pads, notepads, sketchbooks and sketchpads, guided journals, premium stone pens, woodless pencils, watercolor and crayon sets, puzzles, and desk accessories, organized in both individual SKUs and bundles ranging from $9.95 to $195.

The business is differentiated by a deep certification stack — Certified B Corporation, Cradle to Cradle Certified Silver, ISO 14001, ISO 9001, REACH, RoHS, and Carbon Neutral — and by co-branded collections with lifestyle and artist partners including Carhartt WIP, Julie Solvstrom, Mandy Maria, Mark Conlan, and Odujej. The product portfolio carries no embedded software, app, or AI components; value is delivered as a physical good with positioning around sustainability credentials and tactile paper quality.

Karst distributes exclusively through its own Shopify e-commerce storefront and ships worldwide from three warehouses in Los Angeles, Sydney, and Amsterdam, reaching 25+ countries across North America, Europe, and Asia with 2-5 day delivery times in core markets. Revenue is generated on a one-time-purchase model (no subscription disclosed) targeted primarily at individual consumers across three persona segments: general individual consumers for journaling and everyday use, professionals and creatives for premium stationery, and engineers, architects, and designers for technical/grid paper applications. No enterprise customers, wholesale channels, B2B contracts, or institutional investors are disclosed in the input data.

Core offering

Production uses no trees, water, chlorine, or acids, is partly solar-powered, and yields a waterproof, tear-resistant, smoother, and brighter paper than traditional pulp paper. The company sells exclusively through its own direct-to-consumer Shopify e-commerce storefront, shipping worldwide from warehouses in Los Angeles, Sydney, and Amsterdam.
