Very nice quality and appearance
Color: Beige
They were surprisingly stout and went together well. We had to return them because when we took them to where they would be used, they were too big to work in that location. Dang. But if we needed them in the future, I wouldn't hesitate to purchase them.

Good Multi-use Panels
Color: Grey
These panels were easy to assemble and stand sturdy. i will use them to block the sun when I am outside doing yard work in the heat. I'm sure I will find other uses for them too.
