This is a set of three seat covers for a single-seater sofa. The back is elasticated. The actual size is approximately 50cm square, and the thin, stretchy fabric stretches considerably. The color is blue-gray. They have been washed at home and show signs of wear, such as fabric deterioration. They were used as covers to prevent scratches because there is a dog. I will give them to someone who doesn't mind the above. The purchase price was just under 5000 yen for the three.
