These pillows are so comfy! There was minimal odor upon opening them. They came rolled up, and upon releasing them from the packaging, they actually were not flattened for very long. I took  pics of them initially, after me fluffing them, and of one in my queen pillowcase. Its filled! There is additional fluff, but I dont find it necessary for now. Instructions for care also came in the packaging. There is a double layer before the fluff, but Im going to add pillow protectors in between these and my pillowcase.
