Please refer to the photos for the size. The details of the origin and materials are unknown. As shown in the photos, there are some stains and tears on the white edges. Other than that, I think it's still in good condition and can be used for a while. If you have any questions, please feel free to ask. When shipping, I will fold it up to pack it, so there may be creases. Please refrain from purchasing if you are sensitive to these issues or are looking for a new item. For deliveries to Hokkaido, Okinawa, and remote islands of each prefecture, we will basically ship via Yu-Pack with the shipping cost paid by the recipient.
