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.

C.J. Artificial plant arrived broken in 2 places. Stems and leaves are so stiff they stick straight up and cannot be arranged otherwise. Do not buy. Terrible product..

Absolutely Luxurious — The Perfect Cozy Companion!
The black color is deep and elegant, adding a sleek, modern touch to my couch. It’s not just pretty to look at, it’s heavenly to snuggle under. Warm without being heavy, fluffy without shedding, and perfectly sized at 50" x 60", this blanket wraps you in pure comfort whether you’re watching a movie, reading, or just winding down after a long day.
