Porter Classic Kogin Art Zip Up Jacket Color: Blue Size: 3 Condition: No noticeable scratches or stains. Please check the photos for the condition before purchasing. All processing is done by hand by artisans, one piece at a time. This is not the precise and perfect Kogin, but rather the irregularities, distortions, and misalignments of the sashiko stitching on the fabric. That's what makes this PC KOGIN. This is a wonderful piece that pays the utmost respect to the work of many people who are thinking of passing on Japan's proud traditions to the next generation.
