I am absolutely in love with this Purity Home Sustainable-Earth Friendly Pillow Cases. I received it in a Ivory color, standard cases with twin in the set measuring 20 in c 30 in. The cases are environmentally friendly and promotes sustainability with sustainable manufacturing, which combats climate change. It is a beautifully made 100% cotton and 400 thread count pillow case that fit my standard size pillows as if it was made for it. I love that the material is cotton as it provides a cool breathable atmosphere and makes sleeping more comfortable. I am loving this pillow cases and will purchase the entire sheet set.
