White Pillow Protector with Zippers. Select the size and the fabric you want. Custom Pillow Protector (with zipper) made from a choise 200 TC, 300TC, and 440TC (thread count) 100% cotton, and comes in white. The entered dimensions should about 1" wider than the pillow to allow the cover to go on the pillow easily and about the same length as the pillow. All can be machine washed and dried. The pollycotton and the Allergy barrier fabrics don't need to be ironed. (The 200 thread count cotton fabric may need to be ironed to get the wrinkles out.)
