Material: Nylon Features: Gusseted Height: 27cm, Width: 31cm, Gusset: 15cm I've been using this bag for about a year, but I'm selling it now because I haven't been using it recently. It has a lot of storage capacity and a cute check pattern, but I think it gives a neat impression. The surface is laminated, so it's okay in light rain. I've circled the areas of concern with an orange marker, so please check the photos. The stain on the lining is likely from spilled drinks. There is no scuffing on the corners of the bottom. Please understand that this is a used item before purchasing. It will be folded for shipping.
