Small and so cute
This blanket is so cute and perfect for adding a cozy touch to any space! The color is a rich, warm brown that looks great with my other decor. It’s small, but that’s what makes it perfect as an accent piece—it looks amazing draped over a chair or folded on a shelf.
The material feels soft and high-quality. It didn’t have any weird smell after opening it. I would say it should be used more for decoration than everyday use. It adds just the right amount of texture without being bulky or taking up too much space. Works perfect as a drape over side of bed, chair, or blanket ladder.
For the price, I think it’s a great find. It’s stylish, simple, and really ties the room together. If you’re looking for an affordable way to elevate your decor, this is it!

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.
