I enjoyed using my Purity pillowcases. I must say they are so soft, comfortable and beautiful. I love the different colors they have available to choose from. The pillowcases are so soft to my skin. These pillow cases are made of Organic Cotton. I love the size of these pillowcases, they are king size which is 20 in x 40 in. I love the texture of this set of pillowcases. The color is so calm and relaxing. I would buy these set of pillowcases again.
