Beautiful Room Divider
Color: Black
This room divider is so beautiful and elegant yet very functional, study and very well made!
I have had many compliments on its beauty and elegance.
They have said it is much nicer than blurring my background. Which affects how you look on a teleconferencing meeting.
I do zoom meetings at times for my religious meetings when I cannot go in person!
And this is exactly what I have needed to obscure my private bedroom space.
The size is perfect for my size desk. It covers completely the whole area not showing any of my bedroom to the public.
When not in use I fold it up and put it away. It is lightweight and very easy to move around. The height doesn’t make it awkward to move and yet tall enough to obscure my whole background.
MORE IMPORTANTLY~NO ASSEMBLY NECESSARY ‼️
You will not be at one moment disappointed by this purchase instead you will love it!💖💕💖

ZERO regrets purchasing this gorgeous screen!!
Color: Mountains and Waters, Size: 6 Panel, Color: Mountains and Waters, Size: 6 Panel
I am just really blown away by how gorgeous this screen is and I could not be happier with it. It's lighter weight, but still substantial and the print and colors are just exquisite. I would buy this again 10 times over. I can't even believe it just over $200 for a 6 panel screen of this quality and beauty. WELL worth it and the best deal you will see out there for something like this.
The screws and the way they work took a little bit of a learning curve, but once I realized what each controlled, it was smooth sailing. The screen arrives fully assembled, but you just need to tighten and loosen is some areas to accommodate your needs for its position and the floor it's standing on. Nothing too complicated at all, just a few tweaks here and there
