The main material is made of a rare domestic quality Holstein, and is tanned with vegetable tannins to give it durability and elasticity.

Furthermore, when dyeing, a larger amount of oil than usual is allowed to penetrate over time, giving it a good touch and a moist texture.

The finish is finished with only dye, and then the wood grain look that is characteristic of leather is brushed by a craftsman using a kana brush one by one.

Therefore, only about 10 pieces are produced a day, making it a very rare leather.

In addition, the leather rubs to create a glossy finish, allowing you to enjoy the changes over time.
