Kokuyo Trystrams Field Notebook

The Kokuyo Trystrams Field Notebook is a long-standing favourite, now offered in a limited premium colour edition that adds a bright note to a seriously practical design. Originally inspired by traditional survey sketch books, this compact hard cover notebook is built for writing wherever you happen to be — desk or no desk. Slim enough to slip into a suit pocket and sturdy enough to write while standing, it’s made for thinking on your feet, quite literally.

Inside, you’ll find the distinctive light blue 3mm square ruling — known as “sketch” ruling in surveying field books. Subtle yet structured, it’s ideal for sketches, idea memos, mind maps, business trip notes, reading logs, and any page that refuses to stay linear.
