This is a nice comforter and my 5 year-old loves the colors and the pattern. However, no part of it glows in the dark. We even left his lights on for hours and the comforter did not glow. Second, the comforter is not 100% cotton. The label shows that only the outside is cotton. The rest is polyester. That is disappointing because I was really trying to find a cotton comforter. My son likes it enough for me to keep it, but I was definitely disappointed.
