This is a 2-way tote bag that can also be used as a shoulder bag. It's a slightly large size, big enough to fit A4 documents. You can easily fit a lunch box, a cardigan or shawl, and more. It seems like you could even put in things you buy while shopping, so you probably wouldn't need to carry a separate eco-bag. There are no stains or scratches, but there is a slight stain on the handles. The color is a light mocha brown? Please judge the nuanced color from the images.
