“The exquisitely designed @ia notebook arrived today. Stunning. The watermark ruled lines are a fantastic innovation. The binding allows the book to lie flat. Not sure how a marker ribbon might be included in the binding, but that could be a thought for the future? So good I just ordered another, even though it will be a wait for the next batch. Congratulations to the team and the craftspeople involved.” —R. Bigg

FAQs

Why use watermark lines?

The Notebook is a bridge between what you think and the words you write. Any unnecessary elements are visual and mental clutter—including the solid lines you find in most notebooks. Only your words should be on the page, nothing more. However, the page must offer a subtle guiding hand too. We found that delicate watermark lines that recede as you write work wonderfully.

How do the guidelines disappear? Is it invisible ink?

No. The effect is an intended optical illusion, caused by the interplay of light and dark. When you look at a blank page, the watermark guidelines are faint but still clearly visible. As a page fills up with text, the dark ink begins to visually take precedence, causing the watermarks to recede into the background until they’re nearly invisible.

What types of pens work well?

The iA Notebook pairs particularly well with fountain pens. The paper is designed to handle fountain pen ink without bleeding or feathering, ensuring smooth writing and clean lines.

What nibs work best with the Notebook?

We recommend using F (fine) or M (medium) nibs. Japanese fountain pen users usually prefer F due to the delicacy and density of Kanji characters. European fountain pen users typically use M nibs.

Which ink types are best for the Notebook?

Ink choice partly depends on personal preference, but we recommend using a vibrant ink with a strong flow and good absorption. Waterman inks work especially well with the Notebook, while synthetic inks like Pelikan are more likely to smear.

What type of paper does the Notebook use?

The Notebook is made of 81g/m2 Araveal White paper that provides a smooth writing experience with minimal ink bleed-through.

How long until I receive my Notebook?

Delivery times vary depending on the destination. When in stock, items typically arrive within about a week in the U.S. and Europe. Delivery may take longer during busy periods, like the festive season. Once your order has shipped, we’ll send you tracking information, which you can use to check the delivery status.
