Great Sheets!
Size: Twin, Color: Oatmeal
Super soft, wash up beautifully, seem well made — very happy! It’s very hard to find 100% cotton t-shirt type sheets and these are really lovely.

Weirdly textured
Size: King, Color: Dark Gray
I have bought and loved jersey sheets in the past, that have all been as soft as a well worn cotton t-shirt. These arent soft. They have the stretch of jersey, but not the soft smooth texture that they should have. Even after washing a few times these are one of my least favorite sheets I've ever bought on Amazon.

My second pair! ❤️
Color: Brown, Lens Width: 37 Millimeters, Color: Brown, Lens Width: 37 Millimeters
If I could give these glasses ten stars, I would! In fact I just ordered a second pair. I’ve been an Amazon customer for years and this is by far the best deal I’ve ever had. These are legit, well made Harley Davidson sunglasses with the Harley tag attached. They are worth WAY more than the $13 that I paid. They came in a hard shell Harley Davidson case! Last year I bought the same case for my husband’s glasses and the case alone was $14.99! Don’t hesitate to buy these! I was concerned about the size but figured I could return them. The size is perfect and comparable to glasses you’d find anywhere.

Very nice glasses
Color: Brown, Lens Width: 37 Millimeters
These sunglasses are the best glasses I have ever owned. They came with a really nice case. Nice looking, fit very nicely and reasonably priced. I would have gotten a couple more pairs but they sold out. I highly recommend these glasses.
