This is a promotional item I received. I haven't used it and have kept it stored at home. It's a new, unopened item. The size is unknown since it's unopened, but please refer to the photos for surface measurements. Material: Polyester Although unopened, the packaging vinyl has deteriorated due to long-term home storage. Please note that part of the bag is torn (left side of the third photo). It is believed that this will not affect the product itself. Please feel free to ask any questions in the comments. ⚫︎Please understand and agree to the fact that this item has been stored at home before purchasing. ⚫︎Colors may appear different depending on your monitor environment. ⚫︎It will be folded compactly for shipping.
