These Eucalyptus-Tencel Pillow cases of a set are nice, &, beautiful, &, I've loved having them on my bed underneath my head, &, face. They keep your hair from getting staticky, &, frizzy. They allow your hair to breathe better than some other brands of pillow cases. I love the color of gray that I ordered. It goes great with my charcoal blanket. My pillow cases are comfortable, too. Thanks, Olive, And Crate!!
