A notebook made of premium Japanese writing paper with watermarked lines and which handles most pens and inks with ease—including fountain pens.

This innovative notebook features watermark guidelines, which are subtle and unobtrusive and offer direction without distracting. Once your thoughts have taken shape on the page the lines fade into the background, allowing your text to take center stage. It’s an optical illusion, based on the way our eyes work, in that we focus on the highest contrast. Since the ink is stronger than the watermark lines, the watermarks appear to be invisible.

The inner paper is exceptionally smooth and fountain pen-friendly, offering a satisfying writing experience with various tools. The notebook opens completely flat, making it easy to write across the full spread.

Hand-bound in Japan, one by one, and made entirely of paper, the iA Notebook is presented in a finely crafted wooden box—giving it a quiet presence that makes it a meaningful gift.
