This cordovan is not polished, but it has been polished and nurtured by its owner. The deep luster of this leather is unique and cannot be found in other leathers. Shinkihikaku's cordovan is famous for its horse leather. The interior is made of Minerva Box. It is carefully made using the traditional 'Vachetta method’, which has a long history, and is characterized by its expressive natural shrinkage and the way the color and luster improve with use, aging beautifully.
