Thank you for viewing. I'm not an expert on fabrics, but it seems to be a sturdy fabric, perhaps a thin canvas-like oxford cloth. Please refer to the third image for the size. To prevent any issues, please check the images and feel free to ask any questions before purchasing. Please feel free to comment for additional images. There are no noticeable stains on the main body, but please purchase only if you understand that this is a home-stored, used item. I inspect items carefully, but as I am not a professional, there may be oversights. Please refrain from purchasing if you are looking for a perfect item. It will be simply packaged and shipped via Mercari delivery. Please feel free to comment.
