very soft, nice quality. easy to install. definitely measure and make sure it will fit. mine was about 12” long, and this one fits perfectly. more of a soft, washed out pink rather than the brighter pink pictured

Definitely genuine pelts.
Size: 2' x 3' (Natural shape, Sheepksin, Oblong), Color: Ivory White
I like the color. Not too white, more of a natural shade. I ordered two, for each side of the bed. One is larger than the other which proves they are genuine pelts and I’m ok with it!!

Great small size rug
Size: 2' x 3' (Natural shape, Sheepksin, Oblong), Color: Ivory White
Size is great, I wanted to use as a throw on a leather ottoman and it fit great. It isn’t exactly the color I expected but it is a neutral cream. Soft and comfortable. Well made.
