Very Soft Blanket NOT Only For Women and Girls Go For it Guys - BUY THE BLANKET

BEDSURE a seller that is located in CHINA
The product is made in CHINA
The product arrived in a box with a label, stuck on it not like packaging. You would see if you were buying a blanket at a retail store.
Upon removing it from its airtight inner sealed bag, it had a very strong chemical odor to it, and it was very smashed. I placed it in the dryer on high heat for 10 minutes and it really did help to remove the odor and fluff the blanket up.
I'm a little confused why this blanket is only for a woman and girls? At least that's what I had for when I read the title of the listing so I guess if you are a man, you cannot have this blanket kind of odd and if I were the seller, I would change that because it definitely will affect search results...
I used the blanket on top of my bed as an actual comforter. My bed is a full-size bed. I ordered a queen size blanket, and it covers it nicely.
It is probably one of the softest blankets I have ever felt in my life and yes, I would recommend this if you were in the purchase for a nice large, soft, cozy blanket!

Great size, comfortable blanket
Color: Off White, Size: Full
I Love this blanket. It’s so soft and I sleep with it every night. It’s held up well since I’ve purchased it months ago. There’s very minimal shedding/ lint. I would give it a good wash and dry to help with that before using. Great value for money would purchase again. I have a full size bed and it fits very nicely.

FANTASTIC Faux fur blanket! Sooooo perfect!
I purchased this for my Husband to use as he sits in his Lazy Boy recliner chair. He LOVES it! It’s a faux fur that looks and feels REAL! Our dogs love it too lol. It’s so pretty. But the quality is what impressed us. It’s so washable without tearing up. It’s SOFT beyond your imagination! Warmth is really perfect! Not too hot or cold. It’s not light, nor heavy, really a perfect weight. For the price its value is the best you’ll find. I’ve already purchased more as gifts and for myself. All the colors are pretty and realistic. This is a purchase you’ll be proud of. Enjoy.
