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.
