Full of beauty!
Size: 2' x 6' (Sheepskin shape), Color: Creamy White
This company takes pride in their work. The sheep skin covering is beyond what anyone could imagine. I purchased this for medicinal purposes. I found out I have SI joint dysfunction. And this sheepskin helps to relieve pressure points so I am using this as a chair covering for when I sit. The product came in a big box and then a plastic bag and then a third, well covered, plastic bag to protect the sheepskin. You will not be disappointed if you purchase this covering. The price was excellent. It will take your breath away. Very happy with my purchase. There was no odor when I opened the package. Many thanks for an excellent product and helping me to be more comfortable when I sit for short periods of time. :)

Nice, but almost feels faux to me
Size: 2' x 6' (Sheepskin shape), Color: Pink, Size: 2' x 6' (Sheepskin shape), Color: Pink
I like it, but it says it’s real, and I believe them, but it feels like it is faux. I’ve owned a fake one before and it feels similar. Please know I am not saying it is not real. I guess the fake was well done!
It’s super long and I am still on the fence if I want it this long. I’ve taken a pic here, but right now it is wrapped in the package in case I need to return.
It is soft and pretty, but I’m not sure that Barbie pink is my best choice lol. Usually I would pair it with a mid century modern bedspread that is chenille, with a little pink so it works well but not too matchy matchy. I wish I had taken a pic with that bedspread because the bit of pink on the bedspread looks very nice against the rug. So let me apologize for having it with an ugly bedspread.

Exceeded expectations in every way.
Size: 2' x 3' (Sheepskin shape), Color: Gray Tip, Size: 2' x 3' (Sheepskin shape), Color: Gray Tip
I purchased a pair of these a week apart, because the price seemed too good to be true. Instead, they have exceeded my expectations. I own a Buick with leather seats that look incredible, but are not comfortable on long trips, and my wife and I were preparing to leave on a 2200 mile round trip vacation. On the first day, we drove 700 miles, much of it through desert. We were tired when we reached our destination, but comfortable and cool for every mile of it. The sheepskins have made such a difference, that I have never removed them from the car. It is now July, with triple digit temperatures every day, surrounded by desert. The sheepskin keep us cool on every drive. I could have purchased sheepskin seat covers, but these provide the same comfort for a fraction of the cost. Yes, it takes a small amount of effort to adjust them when you first get into the car, but I don't even think about it any more. As far as the quality, there is no shedding, no smell, and no discoloration. We have put over 4,000 miles on the car since I put these in, and I have no complaints to register.

This is What You Need on Those Cold Winter Nights!
Color: White, Size: Throw-50"x60"
This Touchat 1000GSM Faux Fur Throw Blanket is absolutely incredible and one of the softest, coziest blankets I’ve ever owned! The thickness and quality are immediately noticeable the moment you touch it. It feels luxuriously plush, warm, and incredibly comforting.
The faux fur texture is beautiful and looks very high-end, adding a stylish and elegant touch to the room while also being amazingly functional for cold nights. The blanket has a nice heavy weight to it that makes it feel extra cozy and relaxing without being too overwhelming.
I love curling up with this blanket while watching TV, reading, or sleeping. It provides outstanding warmth and comfort and feels like wrapping yourself in pure softness. Even after use, it maintains its fluffy texture and doesn’t shed like some faux fur blankets do.
The quality truly exceeded my expectations. The stitching is well done, the material feels durable, and it looks far more expensive than it actually is. It would also make an amazing gift because it feels so luxurious and comforting.
Highly recommend this blanket to anyone wanting something extra warm, thick, soft, and beautiful for their home. Absolutely worth every penny!
