    Cheap material
    Color: Ivory, Size: Throw(50"x60")
    Does not look like product pictures. Different design and texture. Kept anyway because I chose more for color. After washing a couple of times, these blankets appear VERY worn. They're thinner than preferred and don't wear well. A cheap product for a cheap price. The color was as expected though.

    Comfy but thin-ish blanket
    Color: Pink, Size: Throw(50"x60")
    My friend loved receiving this blanket for her birthday. The color is very true to the picture and makes a great addition to any gift basket. However, it is a little bit on the thin side.

    Soft, warm, cozy
    I absolutely love this blanket. It’s super soft, warm, and very comfortable to use. Perfect for relaxing, sleeping, or just cuddling up at home. The quality feels great and it’s definitely worth the price. Such a cozy purchase—would happily buy again. Thank you, seller! 🧺

    So disappointed… thin and not bubbled or fluffy at all
    I really tried to convince myself that it was a good buy for the price but honestly it’s thinner and less plush than the cheap Walmart throws. It’s soft I guess? But when you buy a bubble blanket you want that bouncy plushness and this is nowhere in the ballpark. The blankets we buy for the dogs are nicer and much cheaper. Epic fail.

    So soft warm and beautiful!!!!
    I have ordered approximately six blankets from you all and have been extremely pleased with each one of them! The colors are so beautiful and the blanket is so soft and warm! I love love the way this particular blanket is made. Not sure how to explain it but it is a little different from the rest of the blankets but whether you get this type or the other types of blankets on this site you will definitely be pleased! My next purchase will be a queen size. I wish they had a king size or even a queen size in this particular blanket but they don't. But I will be ordering a queen size soon. 100% recommend! This blanket is 100% for sure giftable but let me warn you, they are so pretty and soft that you will probably want to keep it yourself so you better order more than one LOL!
