I purchased this as a bedding set and stored it without using it. I believe it's a flat sheet. The size is 168cm x 224cm. I think it can also be used as a cover or for other materials. I believe the material is polyester. It's a smooth, quick-drying material. I'll include one pillowcase with the same pattern. Please purchase if you understand that this item has been stored at home. #DinosaurPatternSheet
