I was looking for a cheaper alternative to buying a silk pillowcase and I am so glad I found this set. For the money it cannot be beat! The cases are very well done and have a zipper to securely zip up the pillow inside. Soft and very easy to care for, I put mine in the washing machine with regular detergent and even bleach (inside out) and in the dryer and they are still looking good (I bought them back in 2011). I would definitely buy more when the need arises as these are a great alternative to expensive silk ones. Though not to be confused, I have a Branche set of pillow cases and they are very luxurious and I must care for them very much and the softness is beyond belief, but for what I need day to day these plain white satin ones do the trick too. Plus if I travel somewhere overnight I take one with me and don't feel guilty if I leave it behind. Hope you enjoy these as much as I have.
