Query: WONDERFUL, BUT...

The pillows themselves, I am on our fourth one, are marvelous. Very comfortable, I love them. The pillowcases are a horse of a different color. The cheap, heavens know where made, zippers break after a couple of uses making the pillowcase useless. It is a shame that such a nice, and expensive, product is made with such cheap garbage. Shame on you "Bucky".
