This is very old cotton that was at my grandfather's house. It was purchased a long time ago at Hankyu Department Store and has been folded and stored ever since. I don't know the details, but I believe it is cotton batting. Since it is old, there are stains and dirt from aging. Please check the photos. Although it is quite old, it is soft and fluffy. I believe it was a high-quality product. Weight: Approximately 250g There are about 8 more of the same item. If you would like one, please let me know in the comments. #CoccoAntiques 220 100
