Leather is a natural material and can discolor. The aged leather matures and looks more beautiful. In particular, unpainted light-colored leathers tan more dramatically. The rubbing areas will darken faster, and the shadows will be darker where you keep them constantly. This is because it absorbs the earth's elements over time, such as movement, sunlight, heat, or the natural oils your body produces. As each S.TAN ages, his soul grows more robust.
