Nice suprise!
Color: Black, Size: Queen
I needed black sheets for a project and these were a very affordable option. I’m shocked how nice these sheets are. After I finished using them for my project and used them for my bed. Very soft and cool to the touch. They washed well and came out of the dryer wrinkle free. The fitted sheet fit my 14” inch mattress perfectly. I think it would even fit if I had a mattress topper as well. The pillow cases were easy to get on my Queen pillows which was nice as I didn’t have to put up a battle! I recommend these sheets.

Color: White, Size: Queen
Best value and best sheet set. Perfect thickness, super soft (but not slippery feeling), extremely durable, and doesn’t wrinkle easy. This sheet set looks nice, feels nice , and is priced excellent. Would recommend to everyone looking for a durable, comfortable set at a wonderful price.

Really great sheet set.
Color: White, Size: Queen
This is the best sheet set we've had in a while. I bought it last year for $15, it's still the same price, and almost a year later it's still intact. It washes and dries well and has a smooth, soft feel. The fitted sheet also stays in place fairly well. They're not cotton but they are still great sheets. I hope they get more colors, like light/soft yellow and lilac/lavender.
