Perfect for sensory sensitive kids and for the pure beauty of it
Size: 2' x 6' (Natural), Color: Natural (Yellow Undertones), Size: 2' x 6' (Natural), Color: Natural (Yellow Undertones)
After speaking over the phone with the seller, I was confident in this purchase for my SPD son. They do not use harsh chemicals or dyes in the process. It is from New Zealand and the only use in Vietnam is for shipping. My son hasn't been diagnosed yet for Autism but he is in the process. He is super sensitive to all things sensory and Amazon feedback isn't the place to give specific details on his condition but I will write that when he fist touched it- which was willingly- he smiled and asked to sleep on it. When he laid down on it and I covered him- he was calm and smiling. In the pic I provided he is calm and holding his door (his obsession is doors and windows). He even set his door down to hold the fur. For other mommies and papas with spd/autistic kids you know that willingly touching a new fabric and setting down an obsessive item is huge and super encouraging! I am so grateful to have such a quality item that is affordable for my special needs son. His older sister received one as well as is now pretending to be a sheep. Fun for everyone! The ONLY negative is that the brand/info sticker on the pelt was a pain to get off and pulled some of the felt - not damaging it but blemishing the unity -but if the skin is down it will not be noticeable. A super fun detail is that all of the fur is combed out but there were a few strands that were wavy and had a slight curl- I LOVED that. There was no odor at all which is great! I expected an animal smell which is better than chlorine or dioxin which is what competitors use in their process. There is no noticeable seam in the middle on the top where the two pelts are gathered. I am soooo satisfied!

Exactly as described and what I needed.
Size: 2' x 6' (Natural), Color: Wolf Tipped
I have a bad back along with other medical problems. I bought this for padding in my wheelchair. Very thick, soft, flexible, everything I needed. No smell and very little shedding even initially. Arrived quickly and well packaged.

High quality sheepskin!!
Color: Natural (Yellow-white Ivory), Size: 2' x 3' (Natural), Color: Natural (Yellow-white Ivory), Size: 2' x 3' (Natural)
This sheepskin was purchased as a "chair cover" for my pets. It arrived with very nice packaging, along with detailed care instructions. The sheepskin was advertised as being"not white" online, and the company made very sure to state that the fur has an "off white/yellow" color. That was a little concerning for me, and I wasn't really sure whether it would have an off color, but it arrived exactly as described. There were no obvious discolorations, spots, or blemishes. In fact, it arrived as a soft "off white" color that is very beautiful and exquisite. The fur has a plush, even look, and there is no matting or fuzzy, "neglected teddy bear look" at all! I actually purchased another brand to see if I could distinguish the difference between the two. This particular sheepskin is by far the better of the two purchases. FYI: When the package was opened, there was no distinct odor. That's a huge plus! I will admit that the size was slightly smaller than expected. It really doesn't matter much in the space I'm using it for though. My miniature Dachshund loves it! If you're trying to find a high quality sheepskin, and you don't need to cover a very large space, this is definitely the one to buy!

The Quality of the sheepskin is awesome.
Color: Wolf Tip, Size: 2' x 3' (Natural)
This rug is a beautiful specimen of New Zealand sheep. The rug is very very soft, the rug is thick, and the brown tips are fabulous looking. All in all I'm very pleased with this purchase. The size is perfect as it measures 2' x 3'. I would buy again from this seller.
