I've been meaning to buy a silk pillowcase for years but they are expensive and not easy to care for. I finally decided to give these a try and I'm very glad I did. Good for my hair, good for my face (no more creases in the morning - I still try to sleep on my back but don't always manage it). And I can just throw the pillowcases in the washer and dryer and they come out great. Very good value.
