A few years ago, I received this item as new and unused from this site. I purchased it for 13,000 yen. Color: Black Material: Soft leather Approximate size (laid flat): Height 26cm, Width 26cm. It seems to have tucks rather than a gusset. Shoulder strap is adjustable, but not removable. Used about 10 times, but it has been stored for a long time, and there is some deterioration over time. Please check the photos. Photo 9: Loose thread on the bottom of the bag? Photo 11: Leather peeling on the shoulder strap? Photo 12: Leather peeling on the top of the bag? etc. I will send it via Takkyubin (courier service).
