Quality drastically lowered over time
Bought a pack of these about 2 years, excellent quality for the price. Thick, soft, would highly recommend. Bought more of these recently, the quality has gone way down hill. It's about half the thickness that it used to be, and feels way cheaper.

Lightweight, Easy to Install, and Holds Up Well
Size: Full, Color: Black
This bed skirt has been a great purchase. It’s very lightweight, which actually made it super easy to put on the bed without a struggle. Once in place, it looks nice and does exactly what it’s supposed to do. It’s also held up well to my almost-teenager being a little reckless at times, no tearing or issues so far. For the price, it’s definitely a good value. Overall, simple, functional, and worth it if you need a clean finished look for your bed.
