At first I was confused and disappointed because they arrive rolled up flat-as-a-pancake in their bags - then you realize they've been vacu-sealed for shipping. After carefully slicing open the package and listening to the low-key alarming desperate ghostly sigh as air once more was pulled into the package, the pillow bloated similarly to how I do at a buffet, and within mere moments it was plump and fluffy. I tossed it in the dryer for about five mins to give it maximum fluffiness, and its amazing! I ... bought the wrong size and need to get bigger ones now, but thats my own fault, the  quality of the pillows themselves is great!
