About the materials
The leather used on the front of the main body is mainly cordovan made from raw hides from France, Spain, and Poland, and vegetable tanned and dyed in Japan. The dye finish is a finish using only dyes, which gives the leather a transparent surface, and the silver surface pattern, which symbolizes the leather's character, is noticeable, resulting in a beautiful, high quality leather finish.
It is tanned and surface-treated by one of only a few tanneries in Japan that specialize in cordovan. The tanning and surfacing processes are carried out by different craftsmen in order to produce a superior cordovan finish. Unlike most leathers, which have intertwined collagen fibers running horizontally, cordovan has collagen fibers arranged in an orderly vertical line. The surface structure of the cordovan layer is the cross section of these collagen fibers.
The fine-grained fibers are exposed in an orderly arrangement, resulting in a very smooth and moist texture.

The leather used for the inner lining is vegetable-tanned leather from PUCCINI ATTAILIO, a tannery in Pisa, Tuscany, Italy. The leather is full vegetable tannin (100% vegetable tanned) and gruzed. Vegetable tanned leather is hand tanned and dyed using a unique traditional Italian process that has been handed down from generation to generation. The leather is slowly infiltrated with oil over a long period of time, which gives it a distinctive smell, a unique color and sheen as it is used, and the oil that has been infiltrated into the leather does not easily come off. It is a very time-consuming and labor-intensive process.
Leather made by this method may get scratches and the color may fade, but on the other hand, the more it is used, the more the scratches fade and the more it is exposed to hand oils and water (rain), the more the leather becomes shiny over time.
