Leuchtturm1917 Outlines - The notebooks that can be used out in the open air to write notes and jot down thoughts, no matter what the weather is like.

The extraordinary thing about these notebooks is the weather proof paper. The paper was developed by a German paper mill for the production of nautical charts. Ships throughout the world are equipped with nautical charts printed on this paper. To combat the rough meteorological conditions at sea, this paper consists of special properties that also make the notebooks in the “Outlines” series weatherproof. The paper is not coated, meaning that the paper can absorb colours and ink just like premium writing paper. However, the special process makes the paper weatherproof. Consequently, paper that becomes wet retains its stiff ness, and a pencil can still be used to write on it.
