Hobonichi Techo A6 Cover Arts&Science: Wax Coating Kip

This Hobonichi Techo cover was created in collaboration with Arts&Science, the shop and brand led by Sonya Park, who also oversees the English-language edition of the Hobonichi Techo, the Hobonichi Techo Planner.

This year’s leather is Wax Coating Kip, a vegetable-tanned kip leather finished with dye. The wax is worked into the surface by hand by craftspeople, drawing out a rich sheen while preserving the natural character of the leather.

The color is a deep, rich dark brown. The interplay of wax and dye creates distinctive variations in tone and a beautiful luster. The more you use it, the deeper the color becomes and the more the shine develops.

This is a techo cover you can nurture over time into something uniquely your own.

The design is kept simple — no metal fittings, just a belt that loops through. Even if your techo grows thicker from adding cards or stickers, you can adjust the belt to keep it shut.

The edges of the leather are left undyed, so the natural kip color shows through as a design accent. On the back, Arts&Science’s signature key motif is stamped into the leather.

It has a pen hook designed to hold a pen by its clip. On the inside, the logos “ARTS&SCIENCE” and “HOBONICHI” are blind-embossed into the leather.
