The snap to put them together.
Color: Coal Black
This came in handy in the foyer. I didn’t want to see the door from my couch. I must be weak found it hard to snap them together. I kept 2 my daughter took the other 2.

I have 2!
Color: Coal Black
My office is in my loft. But there are things along the wall I don’t want to look at. These work great. Hides what I don’t want to see & is a classy look in the room. Sturdy, easy to assemble, well made.

Easy peasy
Size: 1 Panel, Color: Black
Bought this single-panel room divider for my son so he has a little privacy when he has to keep his camera on for online classes.
It’s lightweight, easy to set up, and does the job—he can focus without me photobombing in the background. He can feel like he has his own tiny corner office, even if it’s just the basement.

It serves it's purpose!!
Size: 1 Panel, Color: Black
Product really works well & serves it's purpose! Great height & width. It's flimsy, but it will stand still when put in place.

Zero stars
Size: 1 Panel, Color: Black
The bars are impossible to screw in all the way so it’s not sturdy at all, trash and waste of time
