poorly constructed and not as described. i bought them because they looked nicer than the other pillow protectors i could find. they were more expensive so i gave them a try expecting much better results. after one wash strings were hanging all over the place and they were of very poor quality. i am using them for my hotel and they probably will not make it through the season.
These pillow protectors are great with my new feather pillows that I purchased from Overstock and I also used them on my "old" pillows. If you want to care for your pillows other than just a piloow case, I would recommed these for all bed pillows.
