Super soft and cozy!
Color: Pink, Size: Twin(60"x80")
Love it! Super soft, perfect weight. I bought the pink/dusty rose color and it’s beautiful. I washed it once and did held up and didn’t shed. I will update my review if it starts to fall apart, but so far, very happy with my purchase. The throw blanket seems to be good quality, great price… did I mention I love it?
