I have been searching for satin pillowcases for about a year now, but always held back because of the restrictive pricing at most places. I have very curly hair, and these pillow cases don't completely prevent tangling, but they reduce it A LOT. I washed them after receiving them, and they seem just fine after washing. Like the zipper too, so the pillow doesn't keep slipping out. I was worried that the zipper would poke me while I sleep, but no such problems yet. I purchased in ivory, and it is a very slightly off-white color. I recommend these pillowcases.
