Choose a tree-free, sustainable Hard Cover Notebook with impossibly smooth pages courtesy of Karst.

Made without cutting down a single tree, Karst notebooks also use less water and less energy in the production process. Add in the fact that they're made using recycled calcium carbonate left over from construction and mining, and you've got a new standard in sustainable notebooks. 

And far from just being good for the planet, a Karst notebook is beautiful to use too – Karst Stone Paper has an incredibly smooth texture that ballpoint pens practically glide over, and dazzlingly white pages for incredible contrast. Karst Paper and notebook covers are also superhydrophobic, meaning a spilled glass of water or clumsily-handled coffee won't ruin your writing – the liquid simply rolls off, leaving the pages ready to write on.
