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.

if you are going to be moving them a lot, buy something more sturdy.
Color: Black, Size: Wheel-6 Panel
I use these at our churchc. They are pretty good, not terribly study and the screw that hold the faabric have pulled out in a couple of places. But they wqould work especially well if you were not constantly moving them as we do. They are a bit of a pain to assemble.
