AILONEN Sea Turtle Bedding Set,Sea Turtle Duvet Cover Set King Size,Ocean Turtle Themed Comforter Cover for Teens Boys and Girls(1 Quilt Cover 2 Pillowcases 3 Piece)

Thought it was a warmer blanket when it was really a sheet material.

The other review at this time calls this thin sheet material. Of course it is, it's a duvet cover which means you put your own duvet (such as a thick comforter or goose down duvet, etc.) inside it. It's basically a pillow case for your duvet/comforter. I have this one, but didn't buy it from this seller. There is nothing wrong with it and it doesn't deserve the previous low rating.
