Engineered with obsession
It takes years to test, improve, iterate and perfect even a simple Hardcover Notebook. Every detail of our products have been thought, rethought, overthought, and iterated through. This notebook is where the timeless sophistication of traditional writing tools meet the forward-looking needs of today.
Impervious to liquid.



Infinitely stronger.
Our paper seems to baffle the senses. We’ve heard the writing experience described as buttery, velvety, silky smooth. The lack of plant fibers and grain direction makes writing effortless and hand-cramp free. Unless you write with a kung-fu grip.
Rock beats paper.
To make paper, you make waste. There’s acid. Chlorine. Sulfates. There’s destruction.
Karst begins where this principle ends. We knew more sustainable could also be more durable.
And this led to smooth and waterproof.
If there’s a better way to write, we’ll let you know.
