Unique
Color: 6 Panels Natural Wood, Size: 6 Panels, Color: 6 Panels Natural Wood, Size: 6 Panels
I was looking for something that wasn’t your basic Japanese style black and white cardboard room divider and this checked all my boxes. It looks very nice and stands out without being obnoxious.

Lovely room divider. However, product images did not show the back, which is bare. Let's a perfect amount of light through.

Beautiful Privacy
Color: 6 Panels Natural Wood, Size: 6 Panels
These are lovely screens. I have them in front of my big windows and deck door.
Privacy and beauty. Light weight enough for an old lady to move out of the way, but I never do.
Expect tons of compliments.

It's simply amazing! Great value for money!
It looks incredibly elegant and has a premium feel. At just over $150, it's a steal.

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.
