It’s wonderful!!
Size: 2' x 3' (Single Pelt), Color: Brown, Size: 2' x 3' (Single Pelt), Color: Brown
The product is wonderful! You know it is real, coz the smell doesn’t go away. I use it to meditate and cannot how nicely it created the perfect comforting barrier to help elevate my experience. I however want to find alternatives coz I stopped using animal products after turning a vegetarian. The size (it is bigger in person than in the pic) and color(brown) are perfect for what I do and doesn’t need much/any maintenance! The white however needs a lot of attention and care.I’m sure it would last a decade and the weight is just right too!

Beautiful lux sheepskin, you won't be disappointed!
Size: Single Pelt/2 ft x 3 ft, Color: Grey
I just got this today, 2 day delivery. It's a beautiful silver grey 2'x3', no smell, no shedding, super soft and has a luxurious feel. I can't believe it's real and so affordable! I have it draped on an ottoman in front of the couch. I love it and already want to buy a few more for my mid century modern couch and chairs. So chic! Highly recommend!

Very nice if you aren't too pick on actual color.
Size: Single Pelt/2 ft x 3 ft, Color: Blue
Colors may vary. I really liked this, it was the perfect size and that perfect combination of soft and fluffy, but not being "too fluffy" and looking like a shaggy dog that needed a haircut. My only complaint was the color. Supposed to be blue, and I know monitors and lighting distort stuff but this was an obvious turquoise/teal. Much much greener than I was looking for. I could have made any variant of an actual blue work from powder baby to practically navy, but not this. I had to return, but other than the color, this seemed to be a very nice rug. Sad the color was so off.
