It is a soft black fabric. I don't know the details, but it has a soft, felt-like texture. It was stored in a closet shelf at my parents' house. Its purpose is unknown. Some edges are sewn together, while others are not. Also, it is made by sewing two pieces together. It has been washed. It dries easily, but it wrinkles easily, so I ironed it. *166cm x 183cm *The price includes 750 yen for shipping.
