    I bought these because they were recommended by my hairdresser for hair breakage. I love the zipper because the pillow can’t slip out. I will sy these do feel nice against the skin as well.

    Feels heavenly
    Size: King (20" X 36"), Color: 14 - Lavender - Zipper, Number of Items: 2
    Literally just got it in the mail and fell in love. It's so soft and wasn't being harsh with my beard hair. Hopefully no more split ends! (Good hair protection!) There was no odor to speak of and it fit my pillow perfectly, we got king size, (AKA good compatibility)

    Super soft and worth it
    Color: Light Grey, Size: 2 Pack King(20"X 36")
    Honestly really happy with these pillowcases. They feel super soft and cool when you sleep on them. My hair has been way less messy in the morning too. The quality actually feels pretty nice and the king size fit perfectly. Makes my bed feel a lot more comfortable and expensive looking. Definitely glad I bought them.
