This is a 2-way bag that can be used as a shoulder bag or a backpack. It's made of synthetic leather and is fine in light rain. The synthetic leather is durable. There's a slight discoloration around the zipper, but the inside is clean. There are two small brown stains on the side of the back (see photo 10). It can hold a 500-600mL water bottle, so how about taking it on a day trip! Please purchase if you understand that this is a used item. It will be folded for shipping. Approximate size (measured by a layman): Width: 22cm Height: 25cm Depth: 10cm Handle strap length: approx. 200cm #backpack #shoulderbag #2way #white #travel #cute
