Originally developed for shoes, leather with a water proof effect (water repellency).
If it can be used as a material that works well even when used in bags. With that in mind, we received technology from a German dye maker to make the material suitable for bags, and made improvements. What I was particular about was finishing by carefully kneading a special solution so that not only the surface of the leather but also the contents (core) would be water repellent. An epoch-making leather material that overturns the weakness of leather = water, which is rich in leather-like softness and resistance as a bag material, was born.
