NB Karst Stone Paper A6 Pocket Journal - various colours

Stone paper is genuinely unlike anything else. It's waterproof, tear-resistant, and has a smoothness that makes writing on regular paper feel rough by comparison. 

The A6 format is the sweet spot. Small enough to carry everywhere, substantial enough to be useful. The back pocket for loose notes is the detail customers remember.

The details that matter:
• 144gsm recycled stone paper — 80–90% calcium carbonate, 0% trees
• Waterproof and tear-resistant — genuinely practical, not just a talking point
• Acid-free and bright white — a noticeably premium writing surface
• Thread-bound, never stapled — opens flat, holds together over time
• Back pocket for loose notes and receipts
• A6 format — sized for a coat pocket or bag

About Karst:
Karst started with a simple question: why does paper have to come from trees? Their answer was stone — specifically recycled calcium carbonate, which produces a writing surface that's smoother, more durable, and more sustainable than wood pulp paper. They're B-Corp certified and one of the most recognised sustainable stationery brands in the world.
