Amazing. Ordering more
Color: White, Size: Standard (Pack of 4)
These are amazing and the price is crazy. I'm buying a few more sets. The color is white/white, which I love. They are so soft, not flimsy at all. A great value. Well made, the seams are well sown and the envelope casing even ups the look

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!

These give the benefits of a silk pillowcase on a budget.
Color: White, Size: Standard(20"X 26")
These are very nice pillowcases. Are these made from mulberry silk? I’d have to say no based on the burn test. However if anyone thinks they’re going to get a real mulberry silk pillowcase for this price, they need a reality check. I’ve purchased authentic mulberry silk pillowcases online from between $45 and $105. Most are $70 and up. I’ve bought a number of so called silk pillowcases up to $25. The Infiixso pillowcases are probably the nicest of this latter group. They have the right amount of sheen and the right amount of slip to them. They are very soft and went through the wash well in a mesh bag. I did put them in the dryer and meant to take them out after ten minutes but forgot them; taking them out after about 20 minutes on medium heat. One was a little wrinkly but it was in the mesh bag still. The other one came out fine. These fit my pillows without issue. The zipper seems to be sewn in well. The white is a true crisp white. These sleep cool and my hair glides across them so my hair looks better in the morning than if using a regular non-silk pillowcase.
