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.

SO WORTH THE PRICE
Color: Pink, Size: Queen（20"X 30"）
I bought these in two colors for my new apartment with some new pillows to go on them because I got a whole new set of sheets and comforter for my bed and I have to say these are some of the softest most comfortable cooling pillow cases ever! The silk is not super great quality but for the price it's totally worth it I've noticed that it takes care of my hair better I never used silk pillow cases before... But I don't think I'll ever go back. And the zip closed with a zipper so they stay on your pillow no problem without sliding around and you having to fix them all the time they're so easy to use and they look perfect. They look exactly like the pictures! Definitely worth the price... Oh, and there's no weird smell or anything these are definitely good quality!

Helps hair health.
Color: Lavender, Size: Queen（20"X 30"）
Amazingly soft, cool and comfortable. The sizes are accurate so fit pillows easily. We mixed two colors so our bed looks as comfy and inviting with stylish color blending. Hair seems happy!
