This is a leather zipper case for Traveler's Notebooks, carefully sewn in Japan using domestically produced, vegetable-tanned leather.
The material selected is leather from Himeji, a type of vegetable-tanned leather containing oil, known as oil-tanned leather. It is characterized by its moist texture and the way it develops a rich patina with age.
The leather is thinned down to the millimeter, and the stitching is done right at the edge, resulting in a size that fits perfectly into a Traveler's Notebook, while also achieving thinness and lightness. This zipper case is born from domestic materials and the skills of Japanese craftsmen.
