the non silked part fabric gives way too much and stretches so it's moving all the time and it doesn't adjust to the pillow. The opened ends make move the silk sleeve so it's always moving and not covering all the pillow when you are sleeping and also by moving it produces a lot of wrinkles on the silk part that make it feel it ugly and looks like that you don't make your bed.
if I had known this before, I'd had bought a silk hankerchief or scarf and put on top of my pillow and save the money and it would have work the same or better.
Also my cat just walked on once and it got holes super quickly.
i don't recommend it for the price it has
