Because it is infused with oil, it has a smooth feel and an elegant luster. As you use it, the dye color will fade, and the tannin components in the leather will oxidize, allowing you to enjoy the beautiful color and texture changes over time. *Colors may appear slightly different depending on your monitor and environment. Please understand.
