AMAZING PRODUCT!
I am so impressed by these! It’s winter and my skin has been so sensitive, dry, flaky patches… I’ve tried so many products! I saw a few videos of these being used decided since there were so many independent videos about them I’d try! O.M.G!!! I should have taken a before and after! After only 1 use my face feels sooo much better. No more dry, flakiness. They were extremely easy to use. I have a bit more of a round face and they fit just fine (went up a little higher on my hairline but not bad). Doesn’t leave your skin feeling sticky, just hydrated! 100% will buy again!

Pleasantly surprised!
Color: Beige, Size: 35" x 23"x 3.5"
This bed is thick, plush, soft and has both a furry plush side and a cooler canvas side. It's the perfect size for my dog's crate and he does seem to really enjoy laying on it. It's super easy to clean - washes up nicely on delicate and with a low tumble dry. I had no issues waiting for it to fluff up after being unpackaged, too. It was good to go by that evening. I was expecting, at this price point, something flimsy with loose threads. Overall, I think it's much thicker and nicer than I was expecting for the price! Thinking about grabbing another one before they disappear!
