Tried the Purity Home 400 thread count ultimate percale cotton solid pillowcase in standard and color Ivory and really liked them. These are very soft and keeps you cool. Comes with 2 standard pillowcases in the size 20in x 30in. Fit my pillows perfectly. After a few washes they are still I’m perfect shape and very easy to care for. These are 100% cotton. Machine wash with warm water and tumble dry on low. If a bit wrinkled can always iron a bit. Overall really like them and seem like that will last a long time.
