POLYESTER?!?!
Color: Ivory, Size: 2' x 3' (Pelt), Color: Ivory, Size: 2' x 3' (Pelt)
POLYESTER?!?!
So i just bought several of these. Nice and big and fluffy, looked very clean, very nice. Cats instantly were scared/curious. The back of the skin, the wool, all looked nice, and then I noticed it had a tag on it... The tag says... 100% POLYESTER! What?!?!? This is supposed to be New Zealand Sheep Skin pelt! Shouldnt be any Polyester at all. So, just before I was about to return it, i did a small burn test. I cut off a small bunch of hair and burned it. The fire tried to light but it quickly extinguished itself. And the smell... yes... the smell told me it is REAL WOOL and the fact the fire went out right away also confirms this is not oil based. THIS IS REAL, This is NOT Polyester. I guess also a lot of ppl are returning because of the tag, so these are at a HUGE DISCOUNT!!! BUY THEM UP!!!
They also came in vacuum packed bags, looked nice and kept very nice. These are excellent!
See my photos, the tag, the burned bunch of hair... fire went out, i tried it three times, fire kept instantly going out... smells organic like animal hair when burned, not like oil/polyester. ENJOY!!! I PAID FOR THESE, I was not given anything here!

Love this product!
Color: Linen, Size: 2' x 3' (Pelt)
This sheepskin elevated a boring leather couch to a luxurious sitting space! I purchased 2, one for each loveseat, as sometimes the leather is a little cold. The sheepskin with a small lumbar pillow and voila! A cozy place everyone gravitates to! The sheepskin is soft and cozy and everyone comments they want one! ha probably will get this as a couple of gifts (for those guests that said they wanted one too)

Perfect sheepskin rug
Color: Ivory, Size: 2'3" x 3'5" (Large Pelt)
This sheepskin rug is fabulous! I have it over my office chair and I LOVE it. It does not shed, it stays in place and fits over the seat and up the entire back of the chair with a bit remaining to hang over the edge. My cat sleeps on it every chance he gets. Great value for the price! Just looking at it brings me joy, such a beautiful sheepskin.

Dog ignores, but I like
Color: Ivory, Size: 2' x 3' (Pelt), Color: Ivory, Size: 2' x 3' (Pelt)
I bought this for my dog, who is old and has creaky joints. My dog prefers to continue resting in uncomfortable places that put my plants in peril. He does not ever recline on this dead sheep and looks at me as though I am the sheep slaughterer.
Spouse asked if it came in bigger sizes. Since this is the skin of a dead sheep, it depends on live sheep girth. Anything bigger would likely have to be sewn together from multiple dead sheep.
I find the girth of this sheep pelt perfectly acceptable. It is nice and thick and soft and fairly easy to vacuum. I frequently recline on it when stretched out on the floor, and am grateful it does not leave a mess or make noise like my dog, who should be grateful that his pelt is still attached to his body.

SHRINK Wrapped. NO Customer Support.
Color: Ivory, Size: 2' x 3' (Pelt)
These arrived shrink wrapped and when put down as throw rugs, are lumpy. They are a little less so after 10 minutes on air fluff in the dryer.
They look nice and fit my bedroom well but I’m concerned about walking over them since I prefer a level surface that is even.
Customer support does NOT exist. There appears to be a chat option but there are no responses.
Reading other information, I’ve decided to try a metal comb. So now I’m waiting for that to arrive.
If it wasn’t so difficult to deal with the size difference, I would have simply returned them. I may still and just purchase a return container.
