LeatherCharcoal GrayA5 Cousin Size
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. 
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)

- About the pen hook
The pen hook of this cover is designed to hold a pen by its clip.
- 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.
