The pillowcase itself is fantastic, and I’ve ordered quite a few silk pillowcases. The ‘extras’ make me want to give this a sixth star! At 23 mommes, this is a nice durable weight silk that will stand up to the frequent packing and unpacking of the pillow. It’s as luxuriously silky smooth as you would expect. The zipper closure is absolutely the right option for the travel size too, with the convenience of knowing the pillow will stay put in the case.
