Leather: Charcoal Gray A5 Cousin Size - Techo Lineup

LeatherCharcoal GrayA5 Cousin Size

2025 New

This trifold cover is made of fine charcoal gray leather and has a classic look. The design wraps around your techo, protecting it inside your bag. The small silver snap buttons also create a chic mood.

The leather used for this cover is “Elite,” a chrome-tanned leather produced by Monfrini Pellami. This long-established tannery, founded in Milan in 1898, has been producing leather for fashion and accessory items for four generations. The leather has an elegant, moderately firm surface that exudes the perfect sheen.

The pen hook inside the cover is designed to hold a pen by its clip, and the pen fills out the cover nicely when closed.

The Hobonichi logo is foil-pressed in silver on the inner pocket.

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.

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)

A chic and neutral leather cover

This neutral leather cover suits everyone regardless of gender or age. Since the trifold design looks voluminous, we selected a leather in an exquisite charcoal gray to give it a light impression that matches anyone. The silver buttons create a chic look.

This “Elite” leather was created for elegant and classical fashion. It is firm, fine in texture, and smooth and pleasant to the touch.

The standard charcoal gray color will blend in with anyone on any occasion. We hope you will cherish it for many years.

Please Read Before You Buy

In order to provide you with the most satisfaction for your product, we've compiled a list of warnings, potential issues, and tips to keep in mind for this particular product. Please be sure to read this information carefully before placing your order.

Actual specifications may vary from listing: Each item is individually assembled and sewn by hand by a factory worker. Best efforts are made to ensure consistent sizes and specifications, but there may be slight differences.
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.
Leather coloring stains: Dyed leather products tend to leave stains. Please be careful not to allow the leather to adhere or rub against other objects such as clothing or other belongings, especially if the bag is wet from water or sweat from your hands.
Immediately dry if it gets wet: Immediately dab your product with a dry cloth if it gets wet. Avoid drying it with high temperatures, and place it in a well-ventilated place in the shade.

The cover does not shut tightly: The cover does not shut tightly while it is new, but it will wear in over time.
Not for use with Cover on Cover: The PVC plastic of the Cover on Cover contains plasticizer additives which may cause a reaction in the leather dye and affect the color and quality of the leather cover. Please refrain from using the Cover on Cover with this product.
Avoid storing in hot and humid places: Please avoid storing your product in hot, humid places or placing it atop other objects for long periods of time as this may result in lower quality and color stains.
