The blanket doesn't look or feel like it was ever used, but there are two small gray spots on the back.
Because it looks unused, I didn't want to put it in the washer (still has original fold creases) and hand washing would have left it very wet and my clothes dryer has died, so I am leaving cleaning to the new owner.
There is no material content tag, but it feels like acrylic with a nylon binding.
Measures about 36x48"
