Alettone (Brown) A5 Cousin Size - Techo Lineup

Alettone (Brown)A5 Cousin Size

2025 New

This slim PVC cover has a clear pocket as its main feature. The cover name “Alettone” refers to the part of an aircraft’s wings called an aileron, due to the way the techo cover’s lid can similarly fold shut with a snap. The soft PVC material makes it light and comfortable to carry, while the subdued color scheme gives it a sense of elegance. It closes with a snap button and has a design that fits any user in any setting. Foil-pressed in gold is the thought-provoking message, “Writing by hand is like sending your mind on a journey.”

The flap uses a brown-colored material with a slight texture to give it a feel similar to leather.

The clear pocket on the cover exterior can store your favorite postcards or stickers, or other tools like sticky notes or rulers.

The inner left part of the cover includes a clear pocket that can store cards, while the flap above that can be tucked into your techo and used as a bookmark.

The inner right pocket can fit postcards or tickets, and the pen hook can hold a pen by its clip.

The back of the cover has a large pocket where you can store things you want to access easily, such as a memo pad.

This lightweight cover can make your heart soar as you enjoy writing by hand.

This techo cover is available in A6 size, A5 size, and Weeks size. It also pairs well with the Alettone Document Case you can use to store the HON, documents, and writing utensils.

In the Hobonichi Techo 2025 lineup, the Cousin book comes in either English or Japanese.

*The English book is only available as the January-start version.

A great cover for first-timers

I created this cover as a way to create something that was easy to use for first-timers, with a simple design and attractive price point. There were a lot of colors to choose from, but after a lot of deliberation, I chose this color so it could suit any situation without standing out too much. I wanted something that would be attractive either at work or for personal use, and after a pursuit of attractive form and simplicity, I think it turned out as a chic cover that’s easy to use. Each cover size comes in a different color so anyone using more than one size can enjoy the designs. We recommend using this cover alongside the matching Document Case, which shares the message “Writing by hand is like sending your mind on a journey” to deepen your enjoyment of writing by hand.
