Just Fine Things King/Cal. King Duvet Comforter Cover 6-PCS. Sets in Polyester 3D Grey White Wolf Blue Sky Includes 2 extra pillowcases. This design is reversible. Second side has smaller wolf. The picture here is of the full size set. The queen sized and king sized sets will have a 6 solid sky blue color extension added to the top sides to make them larger. The king sized has a white extension added to the flat sheet. The 3d fabric only comes in a certain width so an extension is necessary for bigger sizes. THIS IS NOT A COMFORTER WITH FILLING! It is a comforter cover.
