A pillowcase protects the pillow from dirt and damage. With the duvet covers standard one or two pillow covers are included but an extra pillowcase is very handy, do not you think? We love a lot of pillows in bed and with the extra pillowcases you can mix and match with the duvet cover. Or when your favorite pillowcase is in the laundry, then the extra pillowcase is really a godsend! Looking for a nice pillowcase in a solid color or with a nice print? With the pillow cases from Essenza you are always good.
