Durable non see through fabric
Color: Black, Size: 4 Panel-88'', Color: Black, Size: 4 Panel-88''
This room divider is exactly what I need. It is very durable and easy to move around. You can’t see through the fabric. I love it. My reason for purchasing this divider is to use as a divider and as a backdrop holder. And it serves both purposes perfectly. It looks much better in person than on camera. It did have the spots on one side on all of them but in a few days they went away. It foldaway and tucked away easily.

Great product
Color: Black, Size: 4 Panel-88''
Love the look of this after it’s put together. It’s pretty sturdy and the connecting clips allow you to shape it different if you need it to fit in a corner. We use this at work so it’s great for the space we use it in. A little hard to store because it doesn’t fold up nicely because of the feet on it but I’m happy with it overall.

Does its job
Color: Black, Size: 4 Panel-88''
For the price the quality is decent. The only thing I do not love is the panels are attached to each other with 3 plastic clips. Only 1 side of the panel is actually attached to wheels. The other side kind of sits on the bar and is held in place with those clips.
