Thank you for viewing. This item was found while cleaning out my parents' house. There isn't a tag or anything on the product, and I don't have any knowledge about it, so I don't know what material it's made of. I also don't know the length of the roll, but the diameter is 5 or 6 centimeters. Please use the photos to make your judgment. If you have any questions, please feel free to leave a comment. Thank you. Also, please read my profile.
