I just received this duvet cover and the King shams. I chose this item because the measurements matched my comforter, and it came with KING SHAMS and not just standard, like many of the other king duvets. These sheets are made in China. The odor was strong when I opened the package, so I washed the items right away, and semi - dried them on medium. Since this is 100% cotton, I like to take them out of the dryer before they're completely dried and smooth them out on the bed to complete the drying so that they don't wrinkle as much. The buttons are not hidden, no big deal. There is a sheen to the fabric, which you either love or hate. I happen to love it. There are two vertical seams on the outer 1/4s of the duvet, I think all King duvets have these, but just be aware of it before you buy.My husband and I are both very pleased with the purchase. The duvet is soft and looks like great quality. I did not shrink when I washed it.
