Pillowcase seems nice. I didn’t read the description closely enough to see it only comes with ONE pillowcase. The photo clearly shows two, which is misleading and the item name states “pillow cases” plural, as if there are two. Then wayyyy down in the description it says pillow cases are sold individually.

Good but slides off pillow

Color: Gray, Size: Standard(Pack of 2)

Ok these are actually cooling and a decent material but they keep sleeping off my pillows and it’s so frustrating. I don’t know if it’s because my pillows and gel memory foam but I cannot keep them on for anything. Because of the price I’m going to keep them just wish they would stay on.
