Hobonichi 2026 A5 Cousin Cover: Leather - TS Basic - Black

We created this black leather cover with graphic designer Taku Satoh, who is in charge of the Hobonichi Techo’s design direction.

TS stands for the initials of Taku Satoh. Out of all the various Hobonichi Techo covers, this has been a staple in our lineup and has been a popular choice for over ten years.

The fine texture of the matte cow leather is soft from the first time you use it and fits comfortably in your hands. The smooth feel as you hold it in your hands is another characteristic of this leather.



The leather cover exudes an elegance with a black color that will suit any outfit. It makes it an ideal first-time leather cover and is also perfect for anyone who wants to own a standard leather cover that is simple, chic, and timeless.
