Get ready for a serious pillowfight! This highly detailed, embroidered cotton pillowcase fits an 18" by 35" insert of your choice, but will also accommodate a standard 20" by 35" King size pillow. Featuring a smooth and soft ultrasuede back and invisible zipper, this pillow ensures luxurious comfort as well as bulletproof dreamland security! Fabric samples available! This listing doesn't include an insert, so please convo me if you'd like me to make an insert (down, polifil) for it. Dry clean recommended, but this pillowcase can be washed in cold and laid flat to dry.
