Best Blanket Ever!!
Color: 16- Dusty Pink, Size: Twin (60" X 80"), Color: 16- Dusty Pink, Size: Twin (60" X 80")
I am in LOVE with this blanket. I got the dusty Rose, the color is Spot On to the pics. It's perfect size, I bought the twin size. It's reversible, and is Super Soft. Plus, No Shedding. Well made, perfect blanket, it's thick yet but not overly making it perfect for year round. Definitely, worth the money. I sleep great with it. It's so pretty, I love it. Will but again in other colors as well.

Luxury at its finest. Must have. You will not be disappointed!
Size: Twin(60" x 80"), Color: Tie-dye Coffee
This blanket is a must have! I purchased several to compare and decide which one was going to make the cut. There was absolutely no competition. This is the softest, most luxurious, coziest and authentic looking blanket. I told my sweetheart THIS is the cozy time blanket! Luxury at its finest! I have real vintage for jackets that are extremely luxurious and this rivals them with a clear conscience!Absolutely stunning and extremely high class feeling and appearing. Also semi-heavy and very warm . Upgrade to any space

Great blanket
Size: Twin(60" x 80"), Color: Tie-dye Coffee
Luxurious look. It’s a soft faux fur on the top, with a beautiful and subtle variegated pattern that adds to the lifelike appearance. The inside of the blanket has a velvet feel and creates a cozy vibe. The blanket is a great size. It is well made with quality material with just the right amount of weight to help me relax and fall asleep.
