Perfectly fits my existing king-size comforter. Has one interior tie in each corner. It's basically three full-length pieces of fabric, stitched together vertically to make a top and bottom (two seams on each side). There is one long zipper on one end. Kind of looks like a sheet. Considering people who buy these are not likely to be able to have other more attractive quilts on the bed, it would be a big plus if the comforter cover had at least an interesting woven-in pattern. The white is bright true white.
