I received this product for free in exchange for my review. I’ve had satin pillowcases before, but this is my first time having a silk pillowcase and I could really tell a difference. I have curly hair, so frizzies are a given- but not nearly as much with this pillowcase! I also like that it zips closed, as opposed to being open - as pillowcases tend to slide off even when they are not slippery
