This is a Mezzo Piano lesson bag. It's black with musical notes... I believe it's a standard Mezzo Piano design. I used it for commuting to cram school for six months. While there is a sense of use, there are no noticeable scratches or stains, and I think it's in relatively good condition. The retail price was around 14,000 yen. The shoulder strap that came with the bag at the time of purchase is not included. It's well-made and has many pockets, making it easy to use. This is a used item. Please take a look at the photos and understand before purchasing.
