This Zippers cover is produced by Arts&Science, a brand and shop led by Sonya Park, who is also the creative director of the Hobonichi Techo Planner.
This year’s Arts&Science cover is made with Spanish goat leather with vibrant colors. The cover is treated with wax for a matte finish.
The Scarlet cover features a subdued orange that’s both gorgeous and calming.
The cover interior has pockets for storing cards, business cards, and more.
The front of the pocket is stamped with the logos of Arts&Science and Hobonichi.
The zipper pull uses the same leather as the cover and has a simple design. The metal part contains the letters A&S.
The cover also has a pen holder for storing a pen.
Over extended use, contact with the cover will cause the surface wax to wear down and present a nice, calming sheen on the leather.
This high quality cover has been painstakingly sewn in Japan. Please enjoy experiencing the texture and changes over time from the wax processing.
*The daily pages of the Planner include a quote in English per two-page spread specially chosen from its parent site, the Japanese web magazine Hobo Nikkan Itoi Shinbun, and words of Arts&Science owner Sonya Park. You will be able to enjoy it as a techo book to read.
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.

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)
