I ordered this duvet knowing it was thin from reading the reviews. But I did not think it was going to be this thin. Its as thin as a piece of paper. 
It come in a plastic envelope which had a cut in it. I openened it hoping the duvet wasn't cut. It wasn't but it had a long black stain along where the envelope was cut. I had to wash it 3 times to try to get this stain out. The stain still remains but not as visible. I'm afraid to bleach it because its so thin and it might deterate.
