Opens in three sections like a suitcase. With rubber bands. I used it for a few months, and then stored it in the closet. I'm selling it because I don't plan to use it. There are some scratches on the surface, but they are not very noticeable. Please check the photos (photos 6 and 7) and be sure you are okay with them before purchasing. ・【Size】H 43cm / W 31cm / D 11cm ・【Capacity】18L (Weight 909g) ・A4 files / Compatible with PCs up to 15 inches ・Retail price: 14,850 yen Color: Black系 (Black-based) Stains/tears: None #AfternoonTea #ZeroGravityBackpack Color: Black-based Stains/tears: None
