This is a semi-custom brown leather bag from a shop called ORZO in Kobe. The size is as follows, measured by a layman: Width: 52cm Height: 40cm Depth: 30cm *when expanded Weight: 1kg I bought it about 6 years ago for 20,000 yen and used it for commuting for about 2 years. Tea from my water bottle leaked during my commute and caused a stain. It's large enough to easily fit A4 files. Thank you for your consideration.
