Thank you for viewing. Size: Approximately 40 x 152 cm, with some margin of error. Material: No indication. It's soft and feels good against the skin. I believe it's a material that stretches slightly lengthwise. Please understand this before purchasing. I have stored this at home, so please only purchase if you understand this. I do not have any pets. I do not smoke. The size is shown when the button is undone. When buttoned, it wraps around to about the elbow, so it won't fall off, making it convenient for various uses. I am decluttering.
