The most amazing blanket EVER!!!
I just got this yesterday and I’m obsessed already. It’s the softest thing I’ve ever touched. The reverse side is also a super soft velour-like feel. I got the Marble Charcoal Grey in 60x80. It looks exactly like the photos and it’s truly a bubble design too. Looks so good draped across my bed. And it’s HEAVY! Literally feels like a weighted blanket on top of being unbelievably soft and cozy. Now I want to get the largest size for even more heavy, snuggly bliss. I slept with it last night along with my normal blanket and I fell asleep much quicker than usual. It does shed a bit on my black clothes but I don’t even care lol. The packaging it arrives in makes it wonderfully gift-able and also lets you know it’s a women-owned company. Didn’t arrive with any bad smells either. All the stitching is immaculate, really everything about this blanket is. I got it on a Black Friday deal for $20% off at $51, it’s worth every penny and feels like a steal to be honest. The quality is unmatched. I’ll have to refrain from buying every single color!

Worth every penny
Color: Ivory White, Size: 90"x90"
This blanket is so soft and comforting, I just love it! It arrived sealed in a plastic bag and fluffed up instantly, I briefly put it in the dryer on low and it came out absolutely perfect. There was no odd smell, no loose threads, it was very well made and looks so inviting on my bed! Definitely a great buy that will keep you warm.

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!!
