Take it easy on the trees as you take down notes with the stylish and sustainable Journal Twin Pack A5 from Karst.

With slim profiles and lightweight, water-resistant covers, this pair of tree-free notebooks are an environmentally-friendly option to take to lectures, meetings or on an adventure. Inside the tasteful-colour covers, you'll find 52 perforated pages of Karst's unique Stone Paper - a paper alternative that's made using recycled materials, and requires a fraction of the water and energy used to make traditional paper. 

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.

Each twin pack features one ruled and one plain notebook, making it easy to keep your subjects separate, or dedicate one to drawing and the other to writing down your travel memories - the choice is yours.
