Hobonichi 2026 Weeks: Colors – Cosmo Blue

The Colors series’ simple design lets you enjoy its unique colors to the fullest. The cover uses a textile made for bookbinding, making it smooth and comfortable to the touch.

Cosmo Blue is a chic, navy techo. The year 2026 is foil-pressed onto the cover in silver, twinkling like a small star in space. It’s a basic design that can be used for various occasions.

The cover has been constructed as a light hardcover book with some give to it so it still bends.

Whenever you want to change up the style, we recommend putting on an additional Clear Cover, sold separately.
