I have always heard that silk pillowcases are good for hair and skin so I was so excited to see this one on Wayfair.  I wasn't too happy to find out it had to be handwashed (I'm lazy) so I decided to try it on delicate in my washing machine.  It washed beautifully.  I even dried it on low for about 5 minutes and then let it air-dry the rest of the way.  I have now washed it a second time with the same great results.  I won't ever want to use another pillowcase!  It is so soft and cool.  I think I will particularly appreciate it in the summer.  The zipper on the side is a really neat feature since the pillowcase always stays in place.
