◎ Porter 70th Anniversary Limited Edition Model Waist Bag I've used it to a certain extent, but I don't think there are any noticeable stains. If you need any additional photos, please ask in the comments section. Thank you. The following is a description: [Yoshida Kaban / Porter / Tango Black] This casual series is a Porter 70th anniversary commemorative model, with both the fabric and sewing MADE IN JAPAN. It uses the techniques of "Tango Chirimen," a traditional woven fabric from the Tango region of Kyoto, and has been modernized. Using tightly twisted raw silk, which is woven alternately, the uneven texture of the fabric's surface, called "shibo," is the main characteristic due to the untwisting of the weft threads. It is dyed in a deep black color, known as formal black.
