This is a black Sacoche bag from Yamato Michi, easy to use. It's mostly unnoticeable, but as you can see in photos 5 and 6, faint white streaks appear when strong light is applied (processed to make them more visible). I've had it for about 5 years and used it a few times in Tokyo, and the inside is clean. It's durable, so I think it can still be used for a long time.
