It comes in a big box and the pillows are really high when you first get them. They flatten after a few uses, which I like. Nothing special, but I'm happy with my purchase because I used my O rewards to buy it. It might not fit a pillow sheet at first when it's puffy and fat, but after it flattens out, it'll fit perfectly. And it's not really flat. They're average pillows. The first few nights were annoying because they propped up my head too high, but like I said, after that, it'll be fine.
