Good buy Pillowcases
Color: 08 - Sage Green, Size: King (20" X 36")
I bought these Bedsure king-size pillowcases from Amazon and overall I’m very happy with them. The first thing I noticed was how incredibly soft and smooth the fabric feels. They almost feel silky, which makes them very comfortable to sleep on. When you lay your head down, the material feels cool and gentle on the skin, which I really like.
I also appreciate the zipper closure. It keeps the pillow securely inside the case and makes everything look neat and tidy on the bed. The zipper is hidden well and doesn’t feel bulky or uncomfortable.
The only small downside is that the pillowcases are so smooth that the pillows can sometimes slide around or even slip off the bed a little. However, that’s really just because the material is so silky.
Overall, I would still recommend these pillowcases. They are soft, comfortable, and feel like a nice upgrade compared to regular pillowcases.

These pillowcases are really nice. They're soft and wash well. I really like the pocket on the end. It makes your pillows look nice and neat. The price is good too.

Love the sheets but GOSH THEY STINK
Color: 19 - Forest Green, Size: Queen (20" X 30")
I have the dark green sheets and bought these for extra cases to match. I would give them 5 stars if it weren’t for the fact that they smell absolutely horrible. I am so surprised after reading reviews that more people don’t mention it?! Maybe it’s more prominent in darker colors but I have washed these now 3 different times even with scent beads and still hate the smell. I wish I could accurately describe what it smells like— it’s just not good and for some reason, body heat only exacerbates it and makes the smell even worse and I wake up feeling like a smell like the sheets… which isn’t a good thing.
Besides that, I do really enjoy them. They feel great on your skin and I love the color. I wish the smell didn’t kill them so badly for me ☹️

Comfy soft pillow covers
Color: 02 - White, Size: Queen (20" X 30"), Color: 02 - White, Size: Queen (20" X 30")
Absolutely love these pillow cases! I bought 2 sets. After I received them & washed & dried them they did remain wrinkly. I just went ahead and put them on my pillows & the wrinkles went away. I continue to love the feel, coolness & comfort. Will definitely buy more.

Pillow cases are beautiful and soft, great quality. I had to return them because standard were too small. I am going to order queen instead.
