LeatherTS Basic - BlackA6 Original Size

    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.

    The Hobonichi Techo leather covers are made with all-natural materials that have their own unique appearance. Every leather cover is a one-of-a-kind, all-natural product, so you can feel good knowing your cover is the only one like it in the world. Here are some of the unique characteristics you can expect to find.



    - Markings that naturally occur during an animal’s life:

    Wrinkles, veins, texture, and scratches







    - Characteristics from the manufacturing process of natural leather:

    Dark spots (occurs when components of the leather are exposed to iron in the air during the tanning and dyeing process)

    Please Read Before You Buy

    We’ve compiled a list of warnings, potential issues, and tips to keep in mind for this particular product. Additionally, the color of the product may be slightly different in actuality than compared to how it appeared on a computer or smartphone screen.

    Pen holder fits pens up to 13.5 mm wide

    The pen holder is designed to fit the 12.2 mm (0.48") diameter Jetstream pen offered as a free Hobonichi Store Exclusive Bonus. Pens with certain shapes and materials may be difficult to pull through the holder. The holder can fit pens up to 13.5 mm (0.53") in diameter.

    Leather may contain preexisting wrinkles and marks

    In order to allow customers the enjoyment of all-natural leather, the leather is processed in a way that retains its original feel. This may leave imperfections visible on the surface of the cover, such as wrinkles, scratches, stains, or vein marks.
    Depending on the conditions in which the cover is used, natural oils of the leather may emerge and appear as stains. We ask for your understanding for these naturally-occurring characteristics of genuine leather.

    Color transfer may occur due to friction, pressure, or moisture

    Color may transfer to other items through friction or prolonged contact. This risk increases when the cover is exposed to water or sweat, so please take extra care when carrying it near clothing or other belongings.
