This is a drawstring bag from Jil Sander. It can be used as a backpack or carried over one shoulder. I was told that it was very popular when it was featured in the magazine "Very" when I purchased it at Hankyu Department Store. I haven't used it much, and the leather is not prone to scratches, so I think it's in good condition. There is some slight staining on the inside around the drawstring area. There is a pocket inside. Includes a dust bag.
