OEKO-TEX 100 certified queen pillowcase set includes 2 standard sized pillowcases (20" x 30") with an envelope closure. Bedsure satin pillow cases offer a silk-like smooth quality, and can be easily cleaned. Turn the pillowcase inside out, place it inside a mesh laundry bag, and wash it with a mild detergent for best results. The unique dyeing technique on the satin enhances high color fastness without fading. 100% poly. I have 4 packs with 2 cases each!
