Adjustable drawstring backpack with mesh pocket. - Color: Gray - Size: 37cm x 33cm x 20cm - Design: With mesh pocket - Straps: Adjustable straps - Style: Drawstring design Thank you for viewing. I purchased this from SHEIN a few months ago. I wanted one without a gusset, but I accidentally bought one with a gusset, and I've only used it twice outside. Please check the photos for the spots of dirt on the bottom of the gusset, and please understand that this is a used item before purchasing. There are no other stains besides on the gusset.
