I believe this was a novelty item I received when I purchased something at a store. I've never used it and have been storing it in my closet. It has creases from being folded. Please check the photos for the size. It doesn't have a gusset. It's quite large and can be cinched up like a drawstring bag, so you can use it for various purposes. I will fold it compactly for shipping, so please be aware of any creases beforehand.
