    Bright color & true to size
    Color: Red, Size: Twin(60"x80")
    I ordered red. Color was vibrant although it has a touch of Orange - not the deep red I thought I would get. Funky chemical smell when I opened it - it went away after I spread it out for a few hours. It's soft with hemmed edges. A little thin but OK for the bed I ordered it for. Price was right & I would probably order additional colors if warranted in the future. It arrived quick.

    Cozy Blanket Burrito….awesome!
    Color: Brown, Size: King(108"x90")
    The king size chocolate brown fleece blanket has quickly become my go-to for comfort and style, making it a must-have in my home. It feels like being wrapped in a cloud—if clouds were soft, warm, and available on Amazon. LOL Seriously, the softness is so delightful and drapes perfectly over my king-sized bed, ensuring I stay warm and cozy during those chilly nights, or when my husband tries to steal the covers. Plus, the rich chocolate brown color adds a touch of sophistication to my bedroom, making it look like I've stepped straight out of a home decor magazine—if only my life were so stylish! It also cleverly hides pet hair, so I'm not living in a fur-tastic disaster zone. After multiple washes, it’s still holding up like a champ, remaining soft and pilling-free. In short, this blanket is the perfect blend of warmth and humor—it's not just a blanket; it's a lifestyle choice. Highly recommended for anyone who loves snuggling, practicality, and a bit of style—because let’s be honest, we all need a little extra warmth in life, especially when doing the classic “blanket burrito” on the couch!

    Very soft
    Color: Navy, Size: Twin(60"x80")
    Very soft and comfortable. Appearance is just like it is described. A little smaller than expected but still very good quality and worked for what was needed.
