This is the "PORTER WISE" leather goods series, designed for ease of use, suitable for both travel and everyday use. The main material, horsehide, uses leather called "underlay" that has only been color-adjusted. The raw hides, gathered from various parts of Europe, are finished by a tanner specializing in horsehide, which is rare in Japan. The oil usually used for finishing is added during dyeing and permeates the leather in the drum. By applying friction processing to the surface of the leather, a smooth and very soft texture is created. This leather offers a charm that cannot be found in leather with surface treatments such as embossing or pigments, as it is in an extremely natural state. The subtle color unevenness enriches the expression, and each piece is unique even if they look similar. Also, because it is soaked in oil, you can enjoy the deep aging process as you use it. Black becomes more glossy, and brown and forest green become deeper in color and take on a more subdued atmosphere. The zippers are less likely to fade compared to regular ones, and the teeth are polished for a glossy finish and smooth operation.
