It was unopened, but I didn't know what it was, so I opened it and took pictures. It's a pure white, cotton-like material, so it might be something used for weddings or funerals. I tried a reverse image search, but the AI's answers seemed completely wrong. If anyone knows what this is, please tell me. The size is about 55cm x 43cm, not including the string. It's a shame to throw away something new, unused, and unopened, so I've listed it as a cloth cover for now.
