MCM backpack. This is authentic, purchased from an authorized store in Seoul. It's in beautiful condition, having been used only about 5 times. I haven't used it recently, and it has been stored at home in a dust bag. Size: 40 x 32 x 15 cm This is the largest size. It has a laptop compartment, so it's perfect for school or work. I think it's in good condition, but there may be some minor scratches. Please purchase only if you understand this. Color: Black
