Clutch Bag: PORTER with Strap This bag uses North American steerhide known for its transparency. The supple texture of the leather, which has been infused with oil, is utilized to its fullest, and the edges are finished only with leather, minimizing the use of core materials. Please note that due to the finish that emphasizes the natural texture of the leather, there may be imperfections such as wrinkles, veins, and scratches.
